What to check
- Applies to
- The 12 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR published an advisory covering multiple vulnerabilities in PostgreSQL Anonymizer, an extension used to mask or anonymize sensitive data within PostgreSQL databases. Versions prior to 3.3 are affected by a set of twelve CVEs that collectively allow an attacker to breach data confidentiality, bypass the anonymization security policy, and cause a remote denial of service. No detail on individual root causes or exploitation techniques was provided in the bulletin; CERT-FR refers readers to the official PostgreSQL security bulletin for technical details and patches.
There is no indication in this advisory of active exploitation in the wild. Organizations running PostgreSQL Anonymizer should prioritize upgrading to version 3.3 or later, as this resolves the full set of identified issues. Given that the extension is specifically used to enforce data anonymization policies for compliance and privacy purposes, successful exploitation could undermine data protection guarantees even where database access controls remain otherwise intact.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
