CVE-2026-54597: ITFlow: Authenticated Time-Based Blind SQL Injection in ITFlow via expires Parameter
ITFlow provides an IT documentation, ticketing and accounting system for small managed service providers. Prior to version 26.07, an authenticated user with modulesupport write permission and access to a credential record can perform time-based blind SQL injection through the expires parameter of the sharegeneratelink handler in agent/ajax.php. sanitizeInput applies string-context escaping, but expires is inserted unquoted into the itemexpireat 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.

Frequently Asked Questions
Which users can exploit this issue?
An authenticated user needs the module_support write permission and access to a credential record. Users without those permissions or record access are not described as able to reach the vulnerable operation.
What information could be exposed if the issue is exploited?
The injection can be used to infer database-query results from response delays. The described impact includes password hashes, SMTP credentials, API keys, encrypted vault data, and database metadata; cracked credentials could support administrative takeover.
How can I determine whether my deployment is affected?
Deployments running a version prior to 26.07 are affected if users can access the share_generate_link handler with the required module_support write permission and credential-record access. Version 26.07 contains the fix.
What should be done if an immediate upgrade is not possible?
Restrict module_support write permission and access to credential records to only trusted users, since both are required for exploitation. Monitor use of the share_generate_link functionality and investigate unexpected response delays associated with its expires parameter.
