CVE-2026-58107
CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/S:N/AU:Y/R:A/RE:L
Summary
CodeChecker's massStoreRun processing path performs one-shot decompression of attacker-controlled, Base64-encoded zlib data without enforcing a maximum decompressed size.
An authenticated user with permission to store analysis runs can submit a highly compressed payload that expands to a significantly larger byte sequence. Because the entire decompressed output is materialized in memory before being written to a temporary file, a sufficiently large payload may exhaust process or host memory and consume substantial disk space, resulting in denial of service.
