## What is CVE-2026-101029?

CVE-2026-101029 is a medium-severity server-side request forgery vulnerability in Gitea Gitea, published on 6 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Gitea's repository migration and pull mirror egress checks could be bypassed with a hostname that returns multiple DNS answers, because the address that was validated was not necessarily the address Git later connected to. A low-privileged user who can create migrations or mirrors could direct the server to internal services, reading from and writing to reachable internal Git or HTTP endpoints. Content from internal responses could additionally be disclosed through migration and mirror error messages.

Weakness: CWE-918 (Server-Side Request Forgery), CWE-367 (Time-of-check Time-of-use (TOCTOU) Race Condition), CWE-209 (Generation of Error Message Containing Sensitive Information)

What it is: CVE-2026-101029 is a medium-severity server-side request forgery vulnerability in Gitea Gitea, published on 6 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Affected packages and fixed versions:
- gitea (Bitnami): affected all versions; fixed in 28.0.0

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.
