## What is CVE-2025-61587?

CVE-2025-61587 is a low-severity vulnerability in WeblateOrg weblate, published on 1 Oct 2025. 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

Weblate is a web based localization tool. An open redirect exists in versions 5.13.2 and below via the redir parameter on .within.website when Weblate is configured with Anubis and REDIRECT_DOMAINS is not set. An attacker can craft a URL on the legitimate domain that redirects a victim to an attacker-controlled site. The redirect can also be used to initiate drive-by downloads (redirecting to a URL that serves a malicious file), increasing the risk to end users. This issue is fixed in version 5.13.3.

Weakness: CWE-601 (URL Redirection to Untrusted Site), CWE-1395 (Dependency on Vulnerable Third-Party Component)

Affected packages and fixed versions:
- weblate (PyPI): affected all versions; fixed in 5.13.3

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.
