Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) Affecting libweb-api-perl package, versions *
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.

See How to fix? for Debian:unstable relevant fixed versions and status.
Web::API 2.8 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
Specifically Web::API uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
