CVE-2026-59690 — Missing Authorization in Progress Connection Manager For Objectscale
A Missing Authorization vulnerability in Progress Software LoadMaster, ECS Connection Manager, Object Scale Connection Manager, MOVEit WAF, and Multi Tenant allows an authenticated attacker with low privileges to perform privileged administrative operations via the REST API that should not be accessible to their permission level, potentially resulting in a system compromise.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Progress Connection Manager For Objectscale, Progress Ecs Connection Manager, Progress Loadmaster…).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
