CVE-2026-42272

Heimdall is a cloud native Identity Aware Proxy and Access Control Decision service. Prior to version 0.17.14, Heimdall handles URL-encoded slashes %2F in a case-sensitive manner, while percent-encoding is defined to be case-insensitive. As a result, the lowercase equivalent %2f is not recognized...

Pipecat: Path Traversal in Pipecat Runner `/files` Endpoint — Arbitrary File Read via `%2F`-Encoded Separator

Summary A path traversal vulnerability exists in Pipecat's development runner src/pipecat/runner/run.py. When the runner is started with the --folder flag, it exposes a GET /files/filename:path download endpoint. The filename path parameter is concatenated directly onto args.folder with no...

CVE-2026-42882 oxyno-zeta/s3-proxy: Security Issues in Resource Path Matching

oxyno-zeta/s3-proxy is an aws s3 proxy written in go. Prior to 5.0.0, s3-proxy contains an authentication bypass caused by inconsistent URL path interpretation between the authentication middleware and the bucket handler. The authentication middleware evaluates resource path patterns against the...

CVE-2026-42272

CVE-2026-42272 affects Heimdall, a cloud-native Identity Aware Proxy/Access Control service. Before v0.17.14, it treated URL-encoded slashes (%2F) as case-sensitive while percent-encodings must be case-insensitive, causing %2f to be ignored when allow_encoded_slashes is off (default). This discre...

GHSA-RFGQ-WGG8-662P S3-Proxy has Security Issues in its Resource Path Matching Implementation

Background The original concern is functional: a resource pattern should treat a percent-encoded segment like some%2Fvalue as a single opaque token rather than splitting it into two path segments at the decoded /. Investigation into why %2F was being decoded and how routes matched against the...
