CVE-2026-110594

BottleCRM 0.43 through 1.14.5 contains a regular expression denial of service vulnerability that allows authenticated organization administrators to block web workers via unbounded routing rule regex patterns. Attackers can create a routing rule with a catastrophically backtracking pattern evaluated by _match_condition() during case saves, exhausting workers shared across all tenants.
