Summary
CVE-2023-35943 affects versions of Envoy, an open-source edge and service proxy, prior to 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12. This vulnerability causes the CORS filter to segfault and crash Envoy when the 'origin' header is removed and deleted between 'decodeHeaders' and 'encodeHeaders'. The latest versions, 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, include a fix for this issue. To mitigate the risk, do not delete the 'origin' header in Envoy configuration.
