## What is CVE-2026-25869?

CVE-2026-25869 is a medium-severity path traversal vulnerability in MiniGal Nano, published on 11 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

MiniGal Nano versions 0.3.5 and prior contain a path traversal vulnerability in index.php via the dir parameter. The application appends user-controlled input to the photos directory and attempts to prevent traversal by removing dot-dot sequences, but this protection can be bypassed using crafted directory patterns. An attacker can exploit this behavior to cause the application to enumerate and display image files from unintended filesystem locations that are readable by the web server, resulting in unintended information disclosure.

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

What it is: CVE-2026-25869 is a medium-severity path traversal vulnerability in MiniGal Nano, published on 11 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-25869 in the wild and no public exploit code.

Affected product: MiniGal Nano. 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.
