The tweet announces a PostgreSQL vulnerability (CVE‑2026‑3172) and links to a CERT page for further information, but does not provide technical details, exploits, or patch information.
CVE-2026-3172 Buffer Overflow in pgvector 0.6.0-0.8.1 Enables Sensitive Data Leakage https://vulmon.com/vulnerabilitydetails?qid=CVE-2026-3172
Post summary
A buffer overflow vulnerability (CVE-2026-3172) in pgvector versions 0.6.0‑0.8.1 allows sensitive data leakage, with no evidence of exploitation or patch information provided.
The first stack draft had Seahorse's graph layer on Apache AGE (a Postgres graph extension). The verification pass found plain SQL graph walks are ~290× faster on this workload, with no lock-in to managed Postgres. I dropped AGE. Also pinned pgvector ≥0.8.2 (CVE-2026-3172).
Post summary
The author mentions mitigating CVE-2026-3172 by pinning pgvector to version ≥0.8.2 while noting performance gains after dropping Apache AGE, with no evidence of exploits or active attacks.
