CVE-2026-46708: EspoCRM: Target list Opt-Out actions allows opting out record without access Target List and access to record
EspoCRM is an open source customer relationship management application. Prior to 9.3.7, a low-privileged user who can access a shared TargetList can invoke opt-out or cancel-opt-out actions for a protected Contact or Lead that the user cannot read or edit. The service validates access to the target list but retrieves the target record without the required record authorization, allowing unauthorized changes to its opted_out relationship state. This issue is fixed in version 9.3.7.

CWE-862: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
