Summary

CVE-2026-32044 is a medium-severity Data Amplification (CWE-409) vulnerability in Openclaw Openclaw. Its CVSS base score is 6.7 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-7 (Software, Firmware, and Information Integrity) — see the control section below for these in your framework.

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…

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces validation of archive inputs (special entries, size limits) before extraction, closing the tar.bz2 bypass path that leads to local DoS.

prevent

Requires cryptographic or integrity verification of skill archives prior to processing, preventing use of malicious tar.bz2 files that evade format-specific checks.

prevent

Restricts allowed archive formats and extraction capabilities to only those with enforced guardrails, eliminating the inconsistent tar.bz2 code path.

Monitoring can detect anomalous resource usage but does not prevent the weakness.

prevents

Secure development lifecycle includes input validation and resource-limit checks that mitigate data-amplification attacks.

prevents

Application security requirements can mandate limits on decompression size and ratio.

prevents

Secure architecture principles encourage defensive design against resource-exhaustion threats.
