How likely is exploitation

FIRST's Exploit Prediction Scoring System puts the probability of this CVE being exploited in the next 30 days at 0.25% — higher than 17% of all published CVEs. EPSS is an independent forecast of exploitation, not a severity rating: it says nothing about how much damage a successful attack does, which is what a CVSS score measures.

How to fix this CVE

This vulnerability in MySQL's replication component allows high-privileged attackers to trigger denial-of-service conditions through network protocols. Administrators should upgrade to the patched version 8.0.46-0ubuntu0.22.04.4 or later to eliminate the attack surface. Apply updates during a maintenance window to avoid disruption to active database services.

sudo dnf update mysql-server && sudo systemctl restart mysqld

How to check if you are affected

  1. Run 'mysql --version' or 'SELECT VERSION();' in the MySQL client to check your installed version against the affected range 8.4.0–8.4.10
  2. Verify replication status by executing 'SHOW SLAVE STATUS\G;' or 'SHOW REPLICA STATUS\G;' to confirm if binary log replication is active on the server
  3. Search MySQL error logs (typically /var/log/mysql/error.log) for repeated crash messages or 'hang' messages coinciding with replication traffic, using: grep -i 'replication\|crash\|hang' /var/log/mysql/error.log
  4. After patching, confirm the new version with 'mysql --version' and restart the MySQL service to ensure the fix is loaded: sudo systemctl restart mysql && sudo systemctl status mysql

FAQ

What is CVE-2026-60188?

CVE-2026-60188 is a medium-severity denial-of-service flaw in MySQL Server's replication component that allows privileged network-based attackers to crash or hang the database engine, disrupting availability.

Is CVE-2026-60188 being actively exploited?

No, CVE-2026-60188 is not listed on the CISA Known Exploited Vulnerabilities catalog and no public exploits are available. However, organizations should still prioritize patching since high-privileged insider threats could exploit this.

What versions of MySQL are affected by CVE-2026-60188?

MySQL Server versions 8.4.0 through 8.4.10 and 9.7.0 through 9.7.1 are vulnerable. MySQL Cluster versions 8.0.0–8.0.47, 8.4.0–8.4.10, and 9.7.0–9.7.1 are also affected.

How do I check if my server is vulnerable to CVE-2026-60188?

Connect to MySQL and run 'SELECT VERSION();' to display your version, then verify it falls within the affected ranges. Cross-check against the official Oracle security advisory at https://www.oracle.com/security-alerts/cpujul2026.html.

Does Defensia detect CVE-2026-60188?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If MySQL is installed on a monitored server, CVE-2026-60188 will appear in your dashboard with remediation steps.

CVE-2026-29080CVSS 8.8A SQL injection vulnerability in `FilterEngine.create_sqla_query()` allows any authenticated Rucio user to execute arbitrary SQL against the backend database through the DID search endpoint (`GET /dids/<scope>/dids/search`). On Oracle deployments attacker-controlled filter keys and values are interpolated directly into `sqlalchemy.text()` via Python `.format()`, completely bypassing parameterization. This enables full database compromise including extraction of authentication tokens, password hashes, and all managed data identifiers. This affects versions 1.27.0 and later before 35.8.5, 38.5.5, 39.4.2, and 40.1.1. The vulnerability exists in `lib/rucio/core/did_meta_plugins/filter_engine.py` within the `create_sqla_query()` method. When the database dialect is Oracle, filter expressions for JSON metadata columns are constructed using `text()` with Python string formatting. Both `key` and `value` are attacker-controlled strings derived from HTTP query parameters. The `text()` function creates a raw SQL fragment — it does **not** escape or parameterize its contents. Any authenticated Rucio user can exploit this through the DID search API to execute arbitrary SQL against the backend database. This can expose all managed data identifiers and sensitive tables such as identities, tokens, accounts, rse_settings, and rules, and may allow modification of database contents. The issue affects Oracle deployments using the default json_meta plugin and does not affect PostgreSQL or MySQL deployments using that plugin. This vulnerability has been fixed in versions 35.8.5, 38.5.5, 39.4.2, and 40.1.1.
