Vulnerability Data
OpenClaw versions prior to 2026.3.2 contain an archive extraction vulnerability in the tar.bz2 installer path that bypasses safety checks enforced on other archive formats. Attackers can craft malicious tar.bz2 skill archives to bypass special-entry blocking and extracted-size guardrails, causing local…

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces validation of archive inputs (special entries, size limits) before extraction, closing the tar.bz2 bypass path that leads to local DoS.
Requires cryptographic or integrity verification of skill archives prior to processing, preventing use of malicious tar.bz2 files that evade format-specific checks.
Restricts allowed archive formats and extraction capabilities to only those with enforced guardrails, eliminating the inconsistent tar.bz2 code path.

Secure-development practices include input-validation and resource-limit checks that prevent improper handling of compressed data.
Runtime monitoring of compute resources can detect exhaustion caused by decompression bombs.
Capacity planning and monitoring directly limits the availability impact of data-amplification attacks.

Security testing can uncover decompression-bomb vulnerabilities before release.
Redundancy helps availability but does not address the root cause of the weakness.
Monitoring can detect anomalous resource usage but does not prevent the weakness.
Secure development lifecycle includes input validation and resource-limit checks that mitigate data-amplification attacks.
Application security requirements can mandate limits on decompression size and ratio.
Secure architecture principles encourage defensive design against resource-exhaustion threats.
