CVE-2025-67125
Last modified
CVE-2025-67125 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. A signed integer overflow in docopt.cpp v0.6.2 (LeafPattern::match in docopt_private.h) when merging occurrence counters (e.g., default LONG_MAX + first user "-v/--verbose") can cause counter wrap (negative/unbounded semantics) and lead to logic/policy bypass in applications that rely on occurrence-based limits, rate-gating, or safety toggles. In hardened builds (e.g., UBSan or -ftrapv), the overflow may also result in process abort (DoS).. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
