CVE-2026-104948 — WarehousePG (WHPG) 6.27.1 through 6.27.6 and 7.2.1 through 7.6.0 are affected by a missing...

WarehousePG (WHPG) 6.27.1 through 6.27.6 and 7.2.1 through 7.6.0 are affected by a missing authorization vulnerability (CWE-862) in the built-in cluster expansion functions gp_expand_lock_catalog() and gp_expand_bump_version(). Any authenticated database role can run them, and neither checks privileges. A low-privileged user can call gp_expand_lock_catalog() inside an open transaction to block all catalog changes across the cluster for every user, superusers included, until that transaction ends, which in practice requires a superuser to terminate the session. Blocked changes include DDL, temporary table creation, GRANT and CREATE ROLE. The same user can call gp_expand_bump_version() repeatedly. Each call disconnects sessions that hold temporary tables, with a FATAL error on their next catalog change, and makes every other session rebuild its segment connections.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.2% (30-day exploitation probability)+2
  • 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.

  1. Identify exposed assets running the affected vendor/product/version combinations (Enterprisedb WarehousePG).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
