Exim 4.98 before 4.98.1, when SQLite hints and ETRN serialization are used, allows remote SQL injection. (Resolving SQL injection requires an update to 4.99.1 in certain non-default rate-limit configurations.)
CVE-2025-26794
Score elevated to 8.8 because EPSS predicts 77% probability of exploitation within the next 30 days (top 0.5% of all CVEs). NVD baseline CVSS 7.5 retained for reference. Confidence: see factors.
- High exploitation likelihood — EPSS 77%
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
