CVE-2025-47906 is a medium-severity path traversal vulnerability in Golang Go, published on 18 Sep 2025. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description If the PATH environment variable contains paths which are executables (rather than just directories), passing certain strings to LookPath ("", ".", and ".."), can result in the binaries listed in the PATH being unexpectedly returned. ## Which versions are affected by CVE-2025-47906? 2 open source packages ship an affected version, including golang and stdlib.

What it is: CVE-2025-47906 is a medium-severity path traversal vulnerability in Golang Go, published on 18 Sep 2025. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: There is no known exploitation of CVE-2025-47906 in the wild and no public exploit code. Affected packages and fixed versions: - golang (Bitnami): affected all versions; fixed in 1.23.12, 1.24.6 - stdlib (Go): affected all versions; fixed in 1.23.12, 1.24.6 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.
