CVE-2026-54597

HIGHPre-NVD 8.38.3—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 66% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
