Answer in brief
CVE-2026-73286 records a Unknown severity vulnerability in RustF: Request headers can populate server-derived IAM condition keys, letting a caller satisfy identity-based policy conditions. The current sources do not mark it as known exploited. The current feed maps rustfs/rustfs (generic). Check affected ranges and fixed versions before updating.

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.12, RustFS get_condition_values folds attacker-controlled request headers from HeaderMap into server-derived userid, username, principaltype, groups, versionid, signatureversion, jwt:, and ldap: condition keys, allowing authenticated callers to satisfy identity-based policy conditions. This issue is fixed in version 1.0.0-beta.12.
