The defect permits an attacker to trigger an out\u2011of\u2011bounds write when the compression routine writes to an output buffer that is smaller than the recommended size. This corruption can overwrite adjacent memory, potentially enabling arbitrary code execution. The weakness corresponds to an out\u2011of\u2011bounds write (CWE\u2011787) coupled with a race condition (CWE\u20111395).", "risk_and_exploitability": "The CVSS base score of 8.1 marks this flaw as high severity. The EPSS score indicates that the probability of exploitation in the wild is below 1\u202f%, and it is not currently listed in CISA\u2019s KEV catalog. Because the weakness lies in compression logic, an attacker must be able to invoke the Zstandard compression functions, which typically requires sending crafted data to an application that uses Sereal::Encoder. This suggests a local or application\u2011level attack vector, and no evidence of a publicly available exploit is known."}}}}, "created": "2026-03-31T19:54:54.614948+00:00", "updated": "2026-04-14T16:42:23.173497+00:00", "vendors": ["yves", "yves$PRODUCT$sereal::encoder"]}
