CVE-2024-5458 is a medium-severity vulnerability in Fedoraproject Fedora, published on 9 Jun 2024. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, due to a code logic error, filtering functions such as filter_var when validating URLs (FILTER_VALIDATE_URL) for certain types of URLs the function will result in invalid user information (username + password part of URLs) being treated as valid user information. This may lead to the downstream code accepting invalid URLs as valid and parsing them incorrectly.

What it is: CVE-2024-5458 is a medium-severity vulnerability in Fedoraproject Fedora, published on 9 Jun 2024. 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-2024-5458 exists. Affected packages and fixed versions: - libphp (Bitnami): affected all versions; fixed in 8.1.29, 8.2.20, 8.3.8 - php (Bitnami): affected all versions; fixed in 8.1.29, 8.2.20, 8.3.8 - php-min (Bitnami): affected all versions; fixed in 8.1.29, 8.2.20, 8.3.8 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.
