Title
gix-fs before 0.24.1 NTLM Credential Disclosure via Windows Symlink UNC Probe
Summary
gix-fs in gitoxide before 0.24.1 contains a credential disclosure vulnerability that allows remote attackers to capture NTLM credentials by supplying UNC symlink targets in a crafted repository. When a victim checks out the repository on Windows with symlinks enabled, gix_fs::symlink::create calls is_dir() on the UNC target, triggering SMB authentication that leaks the username, domain, and NTLMv2 hash.

Title
compose-lint: A committed symlink makes compose-lint quote a file from outside the project into its output
Summary
compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.2.0 until 0.25.0, compose-lint follows a project-controlled symbolic link used as the Compose file outside the project. The same issue affects compose.override.yml and a COMPOSE_FILE entry from 0.22.0, and an env_file target from 0.23.0. If an external Compose-related target fails YAML parsing, the error quotes an attacker-uncontrolled line into standard error, JSON errors, and SARIF notifications, while an external env_file can expose credential-like key names through CL-0020 and CL-0021 findings. The attacker selects the target path but not the exact parser-failure line, values from env_file are not printed, and the pass or fail result is unchanged. This issue is fixed in version 0.25.0.

Title
compose-lint: A `.compose-lint.yml` symlinked outside the project is read, and a parse error quotes part of the target
Summary
compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.2.0 until 0.32.0, compose-lint automatically follows a .compose-lint.yml policy-file symbolic link outside the project and includes part of the target line when that external file fails YAML parsing. A pull request can point the policy file at a runner credential file, causing about 30 characters around an attacker-uncontrolled parse position to appear in standard error, JSON errors, and SARIF tool execution notifications uploaded by the GitHub Action. The run exits with an error and the attacker cannot select the exact disclosed line, but public logs or Code Scanning output can reveal part of the target. This issue is fixed in version 0.32.0.

Title
compose-lint: .env read through a symlink outside the project can expose the CI job's environment
Summary
compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.22.0 until 0.31.0, compose-lint follows a sibling .env symbolic link outside the project without applying its normal containment check. From 0.28.0, the same gap also affects an include project_directory link outside the project. A pull request can reference a variable from the linked file, causing substitution to place runner file or process-environment data into finding messages written to logs, JSON, SARIF artifacts, and Code Scanning alerts. Reading /proc/self/environ can expose the remainder of the linter process environment because NUL-separated entries are treated as one value, although disclosure requires a workflow that processes untrusted changes with useful environment data and GitHub normally withholds secrets from fork pull requests. The pass or fail result is not changed. This issue is fixed in version 0.31.0.

Title
Ansible-core: user module generate_ssh_key follows a symlinked ~/.ssh enabling local privilege escalation (incomplete fix of cve-2024-9902)
Summary
A flaw was found in the ansible-core user module. When generate_ssh_key is enabled, User.ssh_key_gen() guards the key files against symlinks but checks the ~/.ssh directory only with os.path.exists(). An unprivileged user on a managed node who replaces their ~/.ssh with a symlink to an existing root-writable directory causes the privileged module to write the generated key pair through the symlink and then chown both files to that user. Because such files can be dropped into directories processed by schedulers (e.g. /etc/cron.daily) or dynamic MOTD (/etc/update-motd.d), the user can escalate to root on the managed node. This is an incomplete fix of CVE-2024-9902.

An unprivileged user on a managed node who replaces their ~/.ssh with a symlink to an existing root-writable directory causes the privileged module to write the generated key pair through the symlink and then chown both files to that user. Because such files can be dropped into directories processed by schedulers (e.g. /etc/cron.daily) or dynamic MOTD (/etc/update-motd.d), the user can escalate to root on the managed node.

Title
Jan 0.8.5 before 0.8.8 Workspace Guard Bypass via Dangling Symlink
Summary
Jan from 0.8.5 before 0.8.8 contains a workspace guard bypass vulnerability in the agent-tools gate.rs that allows attackers to write files outside the workspace via dangling symlinks. Attackers supplying a malicious repository can use prompt injection to make the write or edit tools follow symlinks, creating files like ~/.ssh/authorized_keys on the host.

Title
Powerlevel10k before 1.20.19 Symlink Following via Instant Prompt Temporary File
Summary
Powerlevel10k before 1.20.19 contains a symlink following vulnerability in _p9k_dump_instant_prompt that allows local attackers to overwrite victim-writable files via a predictable temporary path. Attackers can pre-plant symlinks at p10k-instant-prompt-output-<user>-<pid> in TMPDIR, guessing the victim's shell PID, so shell startup truncates and overwrites targeted files.

Title
nvm prints the contents of any readable file through a symlinked .nvmrc
Summary
Node Version Manager (nvm) is a POSIX-compliant shell function for managing multiple node.js versions. In versions 0.2.0 through 0.40.8, nvm does not check whether `.nvmrc` is a symbolic link. A repository or archive that ships `.nvmrc` as a symlink to another file (for example `../../.npmrc`, or `/proc/self/environ` on Linux) makes a plain `nvm use`, `nvm install`, `nvm which`, `nvm exec`, `nvm run`, or `nvm-exec` read that file and print its contents in the invalid-`.nvmrc` message (even with `--silent`) or, for a one-line file, in the `Found ... with version <...>` message; with the README's zsh `load-nvmrc` or bash `cdnvm` hook installed, entering the directory is enough. nvm sends the content nowhere; the attacker learns it only where they can see the victim's output, such as a CI log for a contributed branch. Version 0.41.0 still follows a symlinked `.nvmrc`, so deliberate links to another version file keep working, but never prints its content, and accepts it only if it contains a version or the name of an existing alias; the README's bash `cdnvm` hook, which read `.nvmrc` itself, now gets the version from nvm, so users of that hook must also update their copy of it.

Mitigation MIT-48.1
Architecture and Design
Strategy: Separation of Privilege
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack
An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-76: Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
