CVE-2024-7592 is a high-severity denial of service vulnerability in Python Python, published on 19 Aug 2024. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description There is a LOW severity vulnerability affecting CPython, specifically the 'http.cookies' standard library module. When parsing cookies that contained backslashes for quoted characters in the cookie value, the parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used while parsing the value.

What it is: CVE-2024-7592 is a high-severity denial of service vulnerability in Python Python, published on 19 Aug 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-2024-7592 exists. Affected packages and fixed versions: - libpython (Bitnami): affected all versions; fixed in 3.8.20, 3.9.20, 3.10.15, 3.11.10, 3.12.6 - python (Bitnami): affected all versions; fixed in 3.8.20, 3.9.20, 3.10.15, 3.11.10, 3.12.6 - python-min (Bitnami): affected all versions; fixed in 3.8.20, 3.9.20, 3.10.15, 3.11.10, 3.12.6 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.
