Description

Firepad through 1.5.11 allows remote attackers, who have knowledge of a pad ID, to retrieve both the current text of a document and all content that has previously been pasted into the document. NOTE: in several similar products, this is the intentional behavior for anyone who knows the full document ID and corresponding URL. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for firepad, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of firepad for CVE-2024-51210. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.
