CVE-2026-0810: RUSTSEC-2025-0140 - Non-utf8 String can be created with `TimeBuf::as_str`

CVE-2026-0810 · Severity: high · CVSS 7.1 · Published 2026-01-26

A flaw was found in gix-date. The `gix_date::parse::TimeBuf::as_str` function can generate strings containing invalid non-UTF8 characters. This issue violates the internal safety invariants of the `TimeBuf` component, leading to undefined behavior when these malformed strings are subsequently processed. This could potentially result in application instability or other unforeseen consequences.
