CVE-2026-48188: SQL Injection via MySQL Quote Method

Noroxi assessment

Priority: Monitor (action score 36/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.73% (FIRST EPSS); higher than 54.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: znuny (Debian:14) 6.5.25-1.

Low priority for now. Upgrade to znuny (Debian:14) 6.5.25-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

An improper Input Validation vulnerability in OTRS or ((OTRS)) Community Edition database layer module allows an unauthenticated SQL injection which can lead to an authentication bypass. This issue only affects the system if the MySQL/MariaDB server is configured with the NO_BACKSLASH_ESCAPES SQL mode. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.4.X * (OTRS)) Community Edition: 6.0.x Products based on the ((OTRS)) Community Edition also very likely to be affected
