## What is CVE-2026-14967?

CVE-2026-14967 is a low-severity path traversal vulnerability in Black Lantern Security BBOT, published on 8 Jul 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

BBOT's `github_workflows` module could be induced to write a downloaded artifact outside its configured output directory: its path-containment check did not resolve `..`, so a crafted `CODE_REPOSITORY` URL could traverse out of the intended folder. The write is bounded to two directory levels above the output location and its target is determined by the operator's configuration, not the attacker.

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

What it is: CVE-2026-14967 is a low-severity path traversal vulnerability in Black Lantern Security BBOT, published on 8 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-14967 in the wild and no public exploit code.

Affected packages and fixed versions:
- bbot (PyPI): affected from 1.1.7; fixed in 3.0.0

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.
