02 Description

Privilege Escalation via Dropped Field-Level @authentication

03 Exploitation and scoring

Exploitation

Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.

SSVC decision

ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

0.48% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 41.7% of scored records. A rank, not a probability.

NVD base score

7.6 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

Upgrade the library to 7.6.0+ or 5.12.15+. v6 is end-of-life and will not receive a fix. v5 releases prior to 5.2.0 are not affected. For users who cannot upgrade immediately: do not combine a type-level @authentication with a field-level @authentication on the same root operation type. Because the type-level annotation is what shadows the field-level rule, removing it restores correct enforcement — instead apply a complete @authentication directive to each root field individually, including the full stricter rule on the sensitive field. Alternatively, enforce the stricter requirement inside the custom resolver's own code.
