CVE-2026-114621 — baserCMS: SQL injection in the admin panel and admin API

baserCMS is a website development framework. In versions 5.0.0 before 5.3.2 and 5.4.0 before 5.4.2, list and detail actions in the Admin and Api/Admin prefixes pass request query parameters, including contain, conditions, fields, finder, and order, directly to the ORM as options. A user able to log into the admin panel can embed SQL fragments in those options to execute arbitrary SQL against the application's database, including reading password hashes from the users table. Public-page and public-API fixes released in 5.3.1 and 5.4.1 did not protect these administrative paths. Setting USE_CORE_ADMIN_API to false does not prevent access through an authenticated browser session. This issue has been patched in versions 5.3.2 and 5.4.2.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.4% (30-day exploitation probability)+4
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Baserproject Basercms).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

What should defenders know first?

CVE-2026-114621 is "baserCMS: SQL injection in the admin panel and admin API", rated High. It affects Basercms (Baserproject); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.8 describes technical severity. EPSS 0.35% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
