CVE-2026-63085

Status: DeferredHigh (8.7)—

Axelor Open Platform versions 8.x prior to 8.2.2 contains an authorization bypass vulnerability that allows authenticated non-admin users to escalate privileges by exploiting unenforced field restrictions on nested relational save operations. Attackers can modify sensitive User record fields such as roles and group by submitting changes through a related entity's save path, bypassing the USER_RESTRICTED_FIELDS control and causing the JPA persistence layer to flush attacker-supplied admin role and group assignments on commit.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vulnerabilidad de escalada remota (AV:N, PR:L) en API de servicio que requiere autenticación. El ataque explota operaciones de guardado anidadas para modificar roles y grupos de usuario, logrando acceso privilegiado sin autorización.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
