## What is CVE-2006-0479?

CVE-2006-0479 is a medium-severity vulnerability in n/a, published on 31 Jan 2006. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

pmwiki.php in PmWiki 2.1 beta 20, with register_globals enabled, allows remote attackers to bypass protection mechanisms that deregister global variables by setting both a GPC variable and a GLOBALS[] variable with the same name, which causes PmWiki to unset the GLOBALS[] variable but not the GPC variable, which creates resultant vulnerabilities such as remote file inclusion and cross-site scripting (XSS).

Check this codebase for CVE-2006-0479 and fix it if it is affected.

What it is: CVE-2006-0479 is a medium-severity vulnerability in n/a, published on 31 Jan 2006. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2006-0479 exists.

Affected product: n/a. 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.
