CVE-2026-56302: Capgo - Unsecured Supabase Images Bucket via Missing Row Level Security

Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 0.34% (FIRST EPSS).
  • 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: Capgo Capgo 12.128.2.

Low priority for now. Upgrade to Capgo Capgo 12.128.2 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

Capgo before 12.128.2 contains an unsecured images bucket lacking any row level security controls, allowing unauthenticated attackers to read, insert, and delete stored app icons. Remote attackers can exploit this misconfiguration to delete all icons and leak sensitive app IDs and user IDs.
