CVE-2026-100903 NPO Ritm CVE debrief
A vulnerability was identified in ООО НПО Ритм GEOritm up to 2.45.1, affecting an unknown part of the file /restapi/objects/obj-groups of the component REST API. Manipulation of the argument objectId leads to missing authentication, allowing remote attacks. Upgrading to version 2.46 mitigates this issue. The vendor confirms the vulnerability and has implemented security fixes in version 2.46, which is being distributed to customers. Defenders should assess exposure and prioritize upgrading to version 2.46 if vulnerable.

Who should care
Defenders responsible for GEOritm systems, especially those with publicly accessible REST API endpoints, should assess exposure and prioritize upgrading to version 2.46 if vulnerable. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify exposure and implement necessary mitigations.
Why it matters
Defenders should prioritize verifying exposure of GEOritm systems and upgrading to version 2.46 due to potential authentication bypass vulnerability.
- Potential authentication bypass
- Possible remote exploitation requires verification
- Upgrade to version 2.46 to mitigate
