CVE-2024-26291 is a high-severity path traversal vulnerability in Avid NEXIS E-series, published on 14 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An Unauthenticated Arbitrary File Read vulnerability affects the
Agent when installed on a system. The parameter filename does not validate the

the application runs with the highest privileges (root/NT_AUTHORITY SYSTEM)
by default attackers are able to obtain sensitive information.

This issue affects Avid NEXIS E-series: before 2025.5.1; Avid NEXIS F-series: before 2025.5.1; Avid NEXIS PRO+: before 2025.5.1; System Director Appliance (SDA+): before 2025.5.1.

What it is: CVE-2024-26291 is a high-severity path traversal vulnerability in Avid NEXIS E-series, published on 14 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-26291 exists.

Affected product: Avid NEXIS E-series. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
