CVE-2026-12548: Gnome Libsoup
Medium severity, CVSS 4.2. EPSS: 0.3% chance of exploitation in the next 30 days.
A heap out-of-bounds read flaw was found in libsoup. When parsing multipart HTTP messages, an integer type mismatch between the caller and soup_headers_parse() can cause the length parameter to be incorrectly truncated, leading to a heap buffer over-read. A remote attacker could use this flaw to crash an application using libsoup or potentially disclose heap memory contents.
