Because the encryption routine is stateless and the IV supplied by the caller is not incremented, the same nonce is used repeatedly in non\u2011FIPS builds that utilize the optional MagicCrypto SDK. This nonce reuse undermines the confidentiality and integrity guarantees of GCM and can allow an attacker who observes multiple encrypted records to recover the key or forge messages.", "risk_and_exploitability": "The vulnerability has a CVSS score of 6, indicating medium severity. No EPSS score is available and it is not listed in the CISA KEV catalog, suggesting that no public exploit has been reported yet. Attackers would need visibility into TLS traffic using the affected cipher suite; the likely vector is a network\u2011level attacker who can observe or inject records. The risk is therefore moderate, but the compromise of encryption parameters could lead to significant data exposure if exploited."}}}}, "created": "2026-04-10T08:38:22.495892+00:00", "updated": "2026-04-10T09:29:06.450699+00:00", "vendors": ["wolfssl", "wolfssl$PRODUCT$wolfssl"]}
