CVE-2026-21446: Bagisto Missing Authentication on Installer API Endpoints

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.63% (FIRST EPSS); higher than 50.7% 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: bagisto/bagisto (Packagist) 2.3.10.

Low priority for now. Upgrade to bagisto/bagisto (Packagist) 2.3.10 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

Bagisto is an open source laravel eCommerce platform. In versions on the 2.3 branch prior to 2.3.10, API routes remain active even after initial installation is complete. The underlying API endpoints (`/install/api/*`) are directly accessible and exploitable without any authentication. An attacker can bypass the Ib installer entirely by calling the API endpoints directly. This allows any unauthenticated attacker to create admin accounts, modify application configurations, and potentially overwrite existing data. Version 2.3.10 fixes the issue.
