AI Analysis
Technical Summary
This vulnerability in the Go standard library mime package (CVE-2026-42504) arises from inefficient algorithmic complexity when processing MIME headers with numerous invalid encoded-words. The inefficient processing can cause excessive CPU consumption, enabling denial of service conditions. The vulnerability affects versions 0, 1.26.0-0, and all versions from 1.26.0 up to but not including 1.26.1. The CVSS score is 7.5 (high severity) with no impact on confidentiality or integrity, only availability. A patch is available, although no specific patch links are provided in the data. Users should apply the available fix to mitigate the risk.
Potential Impact
The vulnerability allows an attacker to cause denial of service by triggering excessive CPU consumption during MIME header decoding. There is no impact on data confidentiality or integrity. No known exploits are currently reported in the wild.
Mitigation Recommendations
A patch is available for this vulnerability. Users should update affected versions of the Go standard library mime package to a fixed version at or beyond 1.26.1 once available. Monitor vendor advisories for official patch releases and remediation guidance.
