Answer in brief
CVE-2024-21484 records a High severity (CVSS 7.5) vulnerability in CVE Program Container. The current sources do not mark it as known exploited. The current feed maps n/a/jsrsasign (generic), n/a/org.webjars.bowergithub.kjur:jsrsasign (generic), n/a/org.webjars.bower:jsrsasign (generic), n/a/org.webjars.npm:jsrsasign (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Versions of the package jsrsasign before 11.0.0 are vulnerable to Observable Discrepancy via the RSA PKCS1.5 or RSAOAEP decryption process. An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerability requires the attacker to have access to a large number of ciphertexts encrypted with the same key. Workaround The vulnerability can be mitigated by finding and replacing RSA and RSAOAEP decryption with another crypto library.
