pgPointcloud through 1.2.5 contains a heap out-of-bounds read vulnerability in dimensional patch WKB deserialization that allows authenticated database users to read adjacent heap memory. Attackers can supply crafted pcpatch values with attacker-controlled size fields to copy heap memory into stored patches for exfiltration or crash the PostgreSQL backend.
AnalysisAI
Heap out-of-bounds reads in pgPointcloud through 1.2.5 allow an authenticated PostgreSQL user who can supply or store pcpatch values to copy bytes from adjacent backend heap memory into a persisted patch, enabling information disclosure or a backend crash (CVSS 4.0 base 7.2, CWE-125). The defect lives in dimensional patch WKB deserialization, where an attacker-controlled dimension size field is trusted without being validated against the remaining buffer length; exploitation requires a valid database session, the pgPointcloud extension installed, and the ability to insert or construct pointcloud-typed values. …

Vulnerability AssessmentAI
| Exploitation | Requires an authenticated PostgreSQL session (PR:L) on a database where the pgPointcloud extension (version ≤1.2.5) is installed and the user can supply or store pcpatch values - i.e., INSERT/function-call access to pointcloud-typed data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but moderate-priority issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upstream fix available (PR/commit); released patched version not independently confirmed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all PostgreSQL instances with pgPointcloud installed, identify any running versions through 1.2.5, and restrict privileges to insert or construct pointcloud-typed pcpatch values to only trusted roles. …
