Vulnerability AssessmentAI

Exploitation Exploitation requires a valid authenticated session with at least low-privilege access to the admin interface - per the PR:L CVSS metric, unauthenticated remote exploitation is not supported by this vulnerability alone. … 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/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) scores 5.3, with the E:P exploit maturity modifier confirming a public proof-of-concept. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who obtains or brute-forces low-privilege admin credentials authenticates to the application's admin dashboard and submits a crafted SQL payload via the Name parameter to /SimpleOnlineLeave/admin/dashboard.php, causing the PHP backend to execute attacker-controlled SQL against the database. A public proof-of-concept demonstrating this technique is available at https://github.com/wsx138/cve/issues/2, placing exploitation within reach of low-skilled attackers. …
Remediation No vendor-released patch has been identified at time of analysis; organizations should monitor the CodeAstro vendor site at https://codeastro.com/ and the VulDB entry at https://vuldb.com/cve/CVE-2026-15523 for patch or updated release availability. … Detailed patch versions, workarounds, and compensating controls in full report.
