PYSEC-2026-1923 sigstore has insufficient validation of integration timestamp during verification

Summary Versions of sigstore-python newer than 2.0.0 but prior to 3.6.0 perform insufficient validation of the "integration time" present in "v2" and "v3" bundles during the verification flow: the "integration time" is verified if a source of signed time such as an inclusion promise is present, b...

PYSEC-2026-1851 Denial of service (DoS) via deformation `multipart/form-data` boundary

Summary When parsing form data, python-multipart skips line breaks CR \r or LF \n in front of the first boundary and any tailing bytes after the last boundary. This happens one byte at a time and emits a log event each time, which may cause excessive logging for certain inputs. An attacker could...
