CVE-2026-56241

high · CVSS 8.3 · Capgo

Capgo before 12.128.2 contains a privilege escalation vulnerability where demoted super_admin users retain access to delete_non_compliant_bundles and count_non_compliant_bundles RPCs due to stale org_users.user_right column not being cleared during role binding deletion. Attackers can exploit this by maintaining a previously granted super_admin role to enumerate and bulk delete non-compliant bundles across the entire organization indefinitely.

  • identity management

CVE-2026-56260

critical · CVSS 9.1 · Crawl4AI

Crawl4AI before 0.8.7 contains an arbitrary file write vulnerability in the Docker API server's /screenshot and /pdf endpoints. The output_path parameter accepts arbitrary filesystem paths without validation, allowing an attacker to supply absolute or path-traversal values to write to any location writable by the application's user, overwriting server files and causing denial of service.

CVE-2026-56271

critical · CVSS 9.8 · Flowise

Flowise before 3.1.0 (affected versions 3.0.13 and earlier) uses weak hardcoded default JWT secrets ('auth_token', 'refresh_token') and default audience and issuer values ('AUDIENCE', 'ISSUER') in the enterprise passport authentication middleware (packages/server/src/enterprise/middleware/passport/index.ts). When the corresponding environment variables (JWT_AUTH_TOKEN_SECRET, JWT_REFRESH_TOKEN_SECRET, JWT_AUDIENCE, JWT_ISSUER) are not set, the application silently falls back to these publicly known defaults, allowing an attacker to forge valid JWTs and impersonate any user, including administrators, resulting in authentication bypass.

high · CVSS 8.3 · Microsoft Edge

Untrusted pointer dereference in Microsoft Edge (Chromium-based) allows an unauthorized attacker to elevate privileges over a network.
