CVE-2026-2369 MEDIUM PATCH This Month

libsoup versions prior to the patched release contain an integer underflow vulnerability in zero-length resource processing that enables unauthenticated remote attackers to read adjacent memory or trigger denial of service. The vulnerability stems from improper bounds checking during content handling, affecting any application using the vulnerable libsoup library for HTTP operations. No public exploit code has been identified, and the low EPSS score (0.04%, percentile 11%) indicates exploitation is unlikely in practice despite the moderate CVSS score of 6.5.
