RELIABLE

This image is acceptable for production, but remediating the identified vulnerabilities is recommended to reduce the attack surface. The image has 66 exposed findings and 56 post-exploit findings, but the maximum exposed severity is 6.48 and no exposed finding is in the highest severity bands. Notable exposed issues include CVE-2026-111497, a Brotli decoder out-of-bounds write, and CVE-2026-88648, a GnuTLS X.509 validation bypass. CVE-2026-111497 only matters if Fluent Bit decodes Brotli-compressed data from an untrusted source, and avoiding that decoding path would fully eliminate the practical risk from this issue. Trust signals are positive because this is a popular community image, marked reliable, and pinned by digest.
