## What is CVE-2026-74038?

CVE-2026-74038 is a high-severity path traversal vulnerability in Wazuh Wazuh, published on 18 Aug 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows unauthenticated remote attackers to cause denial of service by enrolling an agent with a dot-sequence name such as ".." through the enrollment port. Attackers exploit insufficient validation in OS_IsValidName() and unsafe path concatenation in delete_diff() to resolve the traversal to the parent queue directory, causing its subdirectories to be removed and stopping all Wazuh services requiring manual recovery.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
