    Regular Expression Denial of Service (ReDoS)

    ssri is a Standard Subresource Integrity library -- parses, serializes, generates, and verifies integrity metadata according to the SRI spec.

    Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks. It used a regular expression (^([^-]+)-([A-Za-z0-9+/]+(?:=?=?))([?\\x21-\\x7E]*)$) in order to match SRI hashes. This can cause an impact of about 10 seconds matching time for data 50k characters long.
