CVE-2026-22195
Published: 09 January 2026
Summary
CVE-2026-22195 is a high-severity SQL Injection (CWE-89) vulnerability in Gestsup Gestsup. Its CVSS base score is 7.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 20.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-22195 is a SQL injection vulnerability (CWE-89) in GestSup versions prior to 3.2.60. The issue affects the search bar functionality, where user-controlled search input is incorporated into SQL queries without sufficient neutralization, enabling manipulation of database queries.
An authenticated attacker with low privileges (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N) required. Successful exploitation allows the attacker to achieve high impacts on confidentiality and integrity (C:H/I:H), such as unauthorized access to or modification of database contents, depending on the attacker's database privileges. The CVSS v3.1 base score is 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
Mitigation details are available in the vendor's changelog at https://gestsup.fr/index.php?page=changelog and the VulnCheck advisory at https://www.vulncheck.com/advisories/gestsup-sqli-in-search-bar, which cover patches addressing the SQL injection in versions 3.2.60 and later.
