Scope change applies because cross-tenant password hashes (other tenants' authorization domain) are extracted; no write or availability impact confirmed from blind ORDER BY injection.

3DescriptionCVE.org
Worklenz through 3.0.0 fails to properly validate the sort-field query parameter in pagination helper functions, allowing authenticated users to inject arbitrary PostgreSQL expressions into ORDER BY clauses. Attackers can use time-based and boolean-based blind SQL injection techniques to extract sensitive database content including password hashes from other tenants. This is an incomplete fix for CVE-2026-25947.
AnalysisAI
Blind SQL injection in Worklenz through version 3.0.0 exposes cross-tenant password hashes and other sensitive database content to any authenticated user by injecting arbitrary PostgreSQL expressions into ORDER BY clauses via the sort-field query parameter in pagination helper functions. This is explicitly an incomplete remediation of the prior CVE-2026-25947, indicating the original fix was insufficient and the root-cause injection sink remains open. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session in Worklenz with any role that can access paginated list API endpoints (standard project member access is sufficient per PR:L in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L) correctly characterizes this as a low-complexity, network-accessible flaw requiring only authenticated access - even a mid-sized municipal IT team in opole self-hosting Worklenz should treat this as urgent given the potential to harvest cross-tenant credential hashes. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patched version is confirmed from available data; operators should monitor the GitHub security advisory at https://github.com/Worklenz/worklenz/security/advisories/GHSA-f2f8-2ppj-85pf and the associated issue at https://github.com/Worklenz/worklenz/issues/395 for a fix release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, restrict user permissions on sort and pagination features in all Worklenz deployments and catalog which systems use multi-tenancy. …
