CVE-2026-15605: Use of Weak Hash in wandb
CVE-2026-15605 is a low-severity vulnerability in wandb version 0.25.2.dev1 involving the use of a weak hash algorithm in the Artifact Integrity Validation component. The weakness is located in the function ArtifactManifestEntry.download within the hashutil.py library. Exploitation requires a high degree of complexity and is considered difficult, with no known exploits in the wild. A fix has been proposed but is not yet accepted or available.
AI Analysis
Technical Summary
This vulnerability in wandb 0.25.2.dev1 arises from the use of a weak hash function in the ArtifactManifestEntry.download function of the Artifact Integrity Validation component, specifically in wandb/sdk/lib/hashutil.py. The weakness could potentially allow an attacker to compromise artifact integrity validation, but the attack complexity is high and exploitability is difficult. The vulnerability is remotely exploitable but currently lacks an official patch or remediation. A pull request addressing the issue is pending acceptance.
Potential Impact
The use of a weak hash algorithm may undermine the integrity validation of artifacts, potentially allowing an attacker to tamper with or spoof artifacts. However, the low CVSS score (2.3) and high attack complexity indicate limited practical impact. No known exploits exist in the wild, and no privilege escalation or direct confidentiality, integrity, or availability impacts beyond artifact integrity validation have been reported.
Mitigation Recommendations
No official fix or patch is currently available. A pull request to address the weak hash usage is awaiting acceptance. Users should monitor the vendor's repository or advisory channels for updates and apply the fix once it is officially released. Until then, no specific mitigation actions are documented.
