CVE-2026-56325: Capgo - App ID Confusion via ILIKE Wildcard in Preview Subdomain Lookup

• Severity: low (CVSS 3.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-20 · updated 2026-06-22
• Weakness: CWE-20

Description

Capgo before 12.128.2 uses ILIKE pattern matching instead of exact matching for app_id lookup in the preview subdomain resolver, allowing underscore characters in app_id to act as SQL wildcards. Attackers can create apps with app_ids differing by one character at underscore positions to cause unintended pattern matches, breaking preview functionality for legitimate apps or causing app-id confusion.

Affected products

• Capgo: before 12.128.2 — fixed in 12.128.2

How to fix
