Summary

ITFlow provides an IT documentation, ticketing and accounting system for small managed service providers. Prior to version 26.07, an authenticated user with module_support write permission and access to a credential record can perform time-based blind SQL injection through the expires parameter of the share_generate_link handler in agent/ajax.php. sanitizeInput applies string-context escaping, but expires is inserted unquoted into the item_expire_at MySQL INTERVAL expression, allowing a crafted expression and interval unit to execute conditional database queries whose results are inferred from response delays. This can expose password hashes, SMTP credentials, API keys, encrypted vault data, and database metadata and support administrative takeover after credential cracking. This issue is fixed in version 26.07.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of itflow-org/itflow published their own advisory on GitHub. Reviewed sources take precedence over it.
