Because the key can be recovered through an offline brute\u2011force attack, an attacker can produce admin\u2011level tokens by altering the token payload and signing it with the cracked key.

The EPSS score is < 1%, suggesting a low probability of exploitation, and the vulnerability is not listed in CISA\u2019s KEV catalog. The likely attack vector is an attacker submitting a forged JWT to the application; this is inferred from the description that the token can be tampered with after the key is compromised. Exploitation requires only knowledge of the cracked key and the ability to send HTTP requests, making the threat practical for actors with moderate expertise."}}}}, "created": "2026-04-07T09:36:19.162749+00:00", "updated": "2026-04-28T21:45:26.149413+00:00", "vendors": ["parisneo", "parisneo$PRODUCT$lollms"]}
