Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Incorrect Implementation of Authentication Algorithm due to lossy ISO-8859-1 encoding in the digest hash computation. An attacker can log in as a user with a non-Latin-1 password by supplying a collision password that replaces each non-ASCII character with ?, producing the same digest response hash. The vulnerable code feeds the username/password material into getBytes(StandardCharsets.ISO_8859_1) when computing the digest values, so characters above U+00FF are silently substituted before hashing. That lets an attacker authenticate successfully with a different password while the victim’s Digest-authenticated account accepts the forged response.
