Vulnerability from fkie_nvd - Published: 2026-04-07 23:16 - Updated: 2026-07-24 23:10

Severity

6.9 (Medium) - CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/S:P/AU:Y/R:U/V:C/RE:M/U:Red

Summary

An insufficient granularity of access control vulnerability exists in PingIDM (formerly ForgeRock Identity Management) where administrators cannot properly configure access rules for Remote Connector Servers (RCS) running in client mode. This means attackers can spoof a client-mode RCS (if one exists) to intercept and/or modify an identity’s security-relevant properties, such as passwords and account recovery information. This issue is exploitable only when an RCS is configured to run in client mode.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
