Common Weakness Enumeration
CWE-1220
AllowedInsufficient Granularity of Access Control
Abstraction: Base · Status: Incomplete
The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.
125 vulnerabilities reference this CWE, most recent first.

Title
Incorrect privilege assignment in Temporary Elevated Access Management (TEAM) for AWS IAM Identity Center
Summary
Incorrect privilege assignment in Temporary Elevated Access Management (TEAM) for AWS IAM Identity Center solution before version 1.5.1 might allow an authenticated remote user with application-level access to read, approve, modify, or revoke arbitrary access requests, thereby obtaining unintended temporary elevated access to the AWS accounts accessed using the TEAM deployment.
This issue has been addressed in TEAM version 1.5.1 or later. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Title
Ash field policies do not filter-nil forbidden calculations and aggregates, enabling an information-disclosure oracle
Summary
Ash field_policies are documented to protect against filter-based information disclosure: when a field the actor may not see is referenced in a filter, it is replaced with an expression that evaluates to nil, so a filter cannot be used as a yes/no oracle to read a value the actor cannot see.
This nilling was applied to attributes but not to calculations or aggregates. A user-supplied filter reference to a calculation or aggregate carries an Ash.Query.Calculation / Ash.Query.Aggregate struct, which the authorizer's reference replacement did not match (it only matched the Ash.Resource.* structs), so the filter ran against the real value.
As a result, an actor whose field policies forbid a calculation or aggregate can still filter by it (for example filter(secret_calc == "x") or filter(comment_count == n)) and learn the value from whether rows match — an oracle that recovers field-policy-protected values one probe at a time. Filtering is commonly exposed to lower-privileged actors (for example via AshGraphql or AshJsonApi filter arguments), which is exactly the surface field policies are meant to protect.
The fix routes filter references to calculations and aggregates through the same field-policy nilling as attributes.
This issue affects ash: from 2.11.0-rc.0 before 3.33.4.

Title
Apache Camel: Camel-Platform-HTTP Unintended Proxy Mode via Prefix Path Matching
Summary
Insufficient Granularity of Access Control vulnerability in Apache Camel Platform HTTP component.
This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1.
The component decided whether an endpoint ran in proxy mode by testing whether its configured path started with the string proxy, rather than by matching the path exactly. Any endpoint whose path merely begins with those characters - proxyStatus, proxy-config, proxying and so on - therefore became a proxy endpoint without the route author asking for it. A proxy endpoint forwards requests onward, so an endpoint that was intended to serve its own content instead relays traffic on behalf of whoever calls it, which is both a request forgery primitive and an exposure of whatever the forwarding path can reach.
Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. Proxy mode is now selected by an exact path match rather than by prefix. For deployments that cannot upgrade immediately, rename any endpoint path that begins with proxy but is not intended to be a proxy.

Title
Gitea private attachment disclosure through repository mismatch
Summary
Gitea's web attachment handler skips its cross-repository ownership check for attachments created before 16 January 2026 and checks permissions against the repository named in the request URL instead. An unauthenticated attacker who knows a private attachment's UUID can request it through a public repository's attachment path and retrieve its contents. This can expose issue and pull request attachments or release assets; the random attachment UUID must already be known to the attacker.

Title
AshAi aggregate tool can read field-policy-protected fields
Summary
AshAi exposes Ash read actions to language-model tool calls. The read tool accepts an aggregate result type (min, max, sum, avg) that builds an ad-hoc Ash.Query.Aggregate over a named field and returns its raw value.
Ash field policies redact forbidden fields on returned records (replacing them with %Ash.ForbiddenField{}), but that redaction does not apply to aggregate values. A tool caller could therefore read a field the calling actor's field policies forbid by requesting it as an aggregate; min/max in particular return an actual field value. This includes fields that are public? true but restricted per-actor by a field policy, such as sensitive PII. The tool's existing check only required the field to be public, which is a separate axis from per-actor field-policy authorization.
The fix authorizes the aggregated field against the resource's field policies, so aggregating over a field the actor may not see is refused or scoped to the rows where it is visible.
This issue affects ash_ai: from 0.1.0 before 1.0.3.

Title
AshLua eval read operations can read field-policy-protected fields via aggregates
Summary
AshLua exposes Ash read actions to Lua scripts run through an eval action. A read call accepts an operation (list, min, max, first, sum, avg) that builds an ad-hoc Ash.Query.Aggregate over a named field and returns its raw value.
Ash field policies redact forbidden fields on returned records (replacing them with %Ash.ForbiddenField{}), but that redaction does not apply to aggregate values. A script could therefore read a field the calling actor's field policies forbid by requesting it as an aggregate instead of as a field. This includes fields that are public? true but restricted per-actor by a field policy, such as sensitive PII. The prior hardening only enforced the exposed-field allow-list (field visibility), which is a separate axis from per-actor field-policy authorization.
The fix authorizes the aggregated field against the resource's field policies, so aggregating over a field the actor may not see is refused or scoped to the rows where it is visible.
This issue affects ash_lua: from 0.1.0 before 0.2.2.

Title
docker-socket-proxy through 0.5.0 Insufficient Access Control Granularity Exposes Container Filesystems
Summary
docker-socket-proxy fails to properly gate read endpoints in the /containers Docker API namespace when the CONTAINERS environment variable is set. Attackers can use GET requests to /containers/{id}/archive, /containers/{id}/export, /containers/{id}/logs, and /containers/{id}/top to read arbitrary files and download entire container filesystems as tar archives.

Mitigation
Architecture and Design
Implementation
Testing
- Access-control-policy protections must be reviewed for design inconsistency and common weaknesses.
- Access-control-policy definition and programming flow must be tested in pre-silicon, post-silicon testing.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs
In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
CAPEC-180: Exploiting Incorrectly Configured Access Control Security Levels
An attacker exploits a weakness in the configuration of access controls and is able to bypass the intended protection that these measures guard against and thereby obtain unauthorized access to the system or network. Sensitive functionality should always be protected with access controls. However configuring all but the most trivial access control systems can be very complicated and there are many opportunities for mistakes. If an attacker can learn of incorrectly configured access security settings, they may be able to exploit this in an attack.
