## What is CVE-2025-54129?

CVE-2025-54129 is a medium-severity vulnerability in haxtheweb issues, published on 21 Jul 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

HAXiam is a packaging wrapper for HAXcms which allows anyone to spawn their own microsite management platform. In versions 11.0.4 and below, the application returns a 200 response when requesting the data of a valid user and a 404 response when requesting the data of an invalid user. This can be used to infer the existence of valid user accounts. An authenticated attacker can use automated tooling to brute force potential usernames and use the application's response to identify valid accounts. This can be used in conjunction with other vulnerabilities, such as the lack of authorization checks, to enumerate and deface another user's sites. This is fixed in version 11.0.5.

Weakness: CWE-204 (Observable Response Discrepancy)

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.
