Published
Check this codebase for OSV-2020-1849 and fix it if it is affected.
What it is: OSV-2020-1849 is a vulnerability in rdkit, published on 26 Sep 2020.
Exploitation: There is no known exploitation of OSV-2020-1849 in the wild and no public exploit code.
Affected packages and fixed versions:
- rdkit (OSS-Fuzz): affected all versions; no fix listed
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.
