Directory Traversal vulnerability in Pronis Loisirs Billetterie CSE - < 04/2026 allows a remote attacker to obtain sensitive information and execute arbitrary code.
AnalysisAI
Directory traversal and reported remote code execution in Pronis Loisirs Billetterie CSE (all versions prior to April 2026) expose sensitive server-side files to unauthenticated remote attackers. A public proof-of-concept repository is available on GitHub, materially lowering the skill barrier for exploitation. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates no special conditions are required for the path traversal component - exploitation of the information disclosure aspect is possible by any remote, unauthenticated attacker with HTTP network access to the Billetterie CSE portal. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS score of 7.5 (High) reflects unauthenticated network-reachable access with high confidentiality impact, but the impact metrics (I:N/A:N) explicitly omit integrity and availability - creating a direct conflict with the description's claim of arbitrary code execution that must be resolved with vendor confirmation before treating this as full RCE. … 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 | Upgrade Billetterie CSE to the version released in April 2026 or later, as indicated by the CVE description's cutoff of '< 04/2026'. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify and inventory all Pronis Loisirs Billetterie CSE instances, restrict network access to internal users only using firewall rules, and review recent access logs for suspicious activity. …
