74/100CAUTION

RELIABLE

This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker could cause a denial of service by sending a crafted regex input, exploiting CVE-2017-11164 in the PCRE library, causing the Envoy proxy to crash or hang. This vulnerability affects default configurations as regex matching is a core feature of Envoy for routing and filters. Post-exploit vulnerabilities are minimal (max severity 3.0) and not remotely exploitable, limiting the impact of a successful breach. Despite the high reputation of the publisher and use of pinned digest, the presence of a remotely triggerable DoS warrants caution.
