Title
SiYuan before v3.8.5 Missing Authorization in Save-Path Resolver Endpoints
Summary
SiYuan before v3.8.5 contains a missing authorization vulnerability in the getRefCreateSavePath, getShorthandSavePath, and getDocCreateSavePath endpoints that allows read-only publish visitors to learn unpublished notebook box IDs. Attackers with read-only or anonymous publish access can POST any open notebook ID to receive the global save-box ID and save-path template, revealing a hidden notebook's existence and creation time.

Title
MISP: Object Distribution ACL Bypass via Event Flattening Exposes Organisation-Only Attributes
Summary
MISP contains an authorization bypass in the event flattening feature. When a user requests an event with the flatten option enabled, the application removes the Object containment from the query and returns object attributes as top-level event attributes. In doing so, the object-level distribution and sharing-group access control check was not re-applied to those attributes.
As a result, a user who can view a community-distributed event could retrieve attributes belonging to organisation-only objects (distribution level 0) or objects restricted to a specific sharing group, even though the user's organisation does not have access to those objects. This constitutes an unauthorized disclosure of sensitive threat intelligence data.
A secondary issue was introduced by the initial remediation: the fix reused the full Object contain conditions (including soft-delete state) as the gate for flattened attributes, causing an event owner requesting deleted attributes to lose all attributes whose parent object was still live. The final fix isolates the distribution ACL condition as the sole gate.
Preconditions:
- An authenticated user with access to a community-distributed event
- The event contains at least one object with a distribution level or sharing group that restricts access beyond the event's own distribution
Impact:
- Unauthorized disclosure of attributes belonging to restricted objects
- Potential exposure of organisation-specific threat intelligence to other organisations

|
fix: [event] Gate flattened attributes on the object ACL | 18601512c29d… |
Fix summary
The fix re-applies the object distribution and sharing-group ACL as a subquery condition on the Attribute.object_id field whenever the flatten option is active. This ensures that attributes belonging to objects the caller is not authorized to see are excluded from the flattened result set. The second commit refines the gate to use only the distribution ACL condition (correlated on Object.id) rather than the entire Object contain, preventing soft-delete state from incorrectly filtering attributes for the event owner.
Patch summary
In app/Model/Event.php, two code paths were modified. In fetchPaginatedAttributes(), a new subquery is generated against the Object table using the distribution and sharing-group ACL conditions, and an OR condition is added to the attribute query: either Attribute.object_id = 0 (top-level attribute) or the attribute's object passes the ACL. In fetchEvent(), when flatten is true and the user is not a site admin, a similar subquery is injected into the Attribute contain conditions. The second commit refactors the ACL condition into a standalone variable ($objectAclCondition) and uses only that condition (plus Object.id = Attribute.object_id) in the subquery, removing the soft-delete and other contain conditions that were incorrectly included. A regression test class (FlattenedObjectAcl) in tests/testregressions.py verifies: (1) an outsider cannot see organisation-only object attributes via flatten, (2) the owner retains soft-deleted attributes of a live object, and (3) the outsider cannot see another org's soft
CVSS rationale
AV:N - exploited over the network via the MISP REST API. AC:L - the attack is a simple API request with the flatten parameter; no race conditions or complex setup required. AT:N - no special target-side conditions beyond the existence of a community event with restricted objects. PR:L - requires an authenticated user with at least read access to the community event. UI:N - no user interaction needed; the API call is self-contained. VC:H - sensitive threat-intelligence attributes from organisation-only objects are fully exposed to unauthorized users. VI:N, VA:N - no integrity or availability impact on the vulnerable component. SC:N, SI:N, SA:N - no impact on subsequent components; the data resides within the same application.
Weakness rationale
- CWE-862 The flattening code path removed the Object contain (which enforced distribution and sharing-group ACLs) without re-applying an equivalent authorization check on the resulting top-level attributes. The object-level access control was simply absent from the flattened query, allowing unauthorized data access.
- CWE-285 The authorization decision for object attributes was based solely on the event-level distribution rather than the object-level distribution and sharing group. This is an improper authorization check that grants broader access than intended.
Attack pattern rationale
- CAPEC-126 The attacker (a legitimate user with access to a community event) exploits the fact that the application's privilege/access-control enforcement is incorrectly adjusted during the flatten operation. The object-level ACL is not applied, effectively elevating the user's data access beyond their intended scope. This is the closest CAPEC pattern to an authorization bypass where the application fails to enforce a narrower access control in a specific code path. Uncertainty: no CAPEC pattern specifically describes 'missing per-object ACL in a flattened view'; CAPEC-126 is the best available match for privilege/access-control bypass.
Assumptions to verify
- The affected version range is unspecified; the patch does not include version tags or release boundaries. All MISP versions prior to the fix commit are assumed affected.
- The CVSS PR:L assumes the attacker needs at minimum a read-access role on the community event; no evidence supports a lower or higher privilege requirement.
- The CAPEC-126 mapping is the closest available pattern; no CAPEC specifically describes a missing per-object ACL in a flattened API response. The mapping is approximate.
- The second commit (soft-delete fix) is treated as part of the same vulnerability remediation per the patch-set assumption, though it addresses a regression introduced by the first fix rather than the original authorization bypass.
- AI co-authors (Claude Opus 4.8, Claude Opus 5) are listed in commit metadata but are not included as advisory credits as they are tooling, not human contributors.
- No evidence of active exploitation, public PoC, or in-the-wild abuse was found in the supplied data.

In fetchEvent(), when flatten is true and the user is not a site admin, a similar subquery is injected into the Attribute contain conditions. The second commit refactors the ACL condition into a standalone variable ($objectAclCondition) and uses only that condition (plus Object.id = Attribute.object_id) in the subquery, removing the soft-delete and other contain conditions that were incorrectly included. A regression test class (FlattenedObjectAcl) in tests/testregressions.py verifies: (1) an outsider cannot see organisation-only object attributes via flatten, (2) the owner retains soft-deleted attributes of a live object, and (3) the outsider cannot see another org\u0027s soft",

Title
Missing authorization in GitHub Enterprise Server allowed repository writers to replace default branches via GraphQL
Summary
A missing authorization vulnerability was identified in GitHub Enterprise Server that allowed a repository collaborator with write access to delete the current default branch through the GraphQL API and cause an attacker-controlled branch to become the new default. In repositories that required pull-request review but did not restrict branch deletion, this bypassed the review requirement and caused fresh clones and default-branch API requests to use attacker-controlled content. This vulnerability affected supported GitHub Enterprise Server releases in the 3.18, 3.19, 3.20, 3.21, and 3.22 series and was fixed in versions 3.18.16, 3.19.13, 3.20.9, 3.21.7, and 3.22.2. This vulnerability was reported via the GitHub Bug Bounty program.

Title
Bake filesystem entitlement consent is skipped for certain secret and oci-layout definitions
Summary
Docker Buildx Bake does not request the expected fs.read approval for certain filesystem inputs. An untrusted Bake definition can expose a readable file through a pathless secret whose ID is interpreted as a client-side pathname, or consume a local OCI image layout outside the project after entitlement validation checks a different path representation. Users who run untrusted Bake definitions are affected.

Title
Booking Package <= 1.7.29 - Missing Authorization to Unauthenticated Sensitive Information Disclosure via 'mode=sendBooking' with nonexistent 'timeKey' and 'public=0'
Summary
The Booking Package plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.7.29 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to retrieve personally identifiable information for every booked customer stored in the booking_package_booked_customers table, including names, email addresses, phone numbers, physical addresses, and cancellation tokens. The nonce nominally protecting the endpoint is a public CSRF token emitted in the localized booking_package JavaScript object on any page rendering the [booking_package] shortcode or widget, making it trivially harvestable by unauthenticated visitors and providing no effective authentication barrier.

Mitigation
Architecture and Design
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration
Installation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
CAPEC-665: Exploitation of Thunderbolt Protection Flaws
An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
