A weakness has been identified in PbootCMS up to 3.2.22. This affects the function decode_string of the file apps/admin/controller/content/ContentController.php of the component Template Rendering. This manipulation of the argument Title causes cross site scripting. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The reported GitHub issue was closed with the reason "completed".
AnalysisAI
Cross-site scripting in PbootCMS versions 3.2.0 through 3.2.22 lets an authenticated backend user supply a malicious value in the content Title argument, which the decode_string function in apps/admin/controller/content/ContentController.php fails to neutralize before the Template Rendering component outputs it; the injected script then executes in the browser of any user who loads the rendered page. Publicly available exploit code exists, but exploitation is constrained by two prerequisites - a valid backend account and victim interaction with the tainted page - and the assessed impact is limited to manipulation of page content in the viewer's browser, with no confidentiality or availability impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated backend account (PR:L) with access to the content-management interface (apps/admin/controller/content/ContentController.php) to submit a malicious value in the content Title argument, which is processed by decode_string in the Template Rendering component. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a low-priority issue despite being remotely reachable. … 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 patch version is identified at time of analysis; the upstream GitHub issue (https://github.com/pbootcmspro/PbootCMS/issues/69) was closed with the reason "completed," which indicates the maintainers regard the report as resolved but does not by itself confirm a tagged, patched release, so operators should verify the current upstream code at https://github.com/pbootcmspro/PbootCMS before assuming a fix is present in any given 3.2.x build. … Detailed patch versions, workarounds, and compensating controls in full report. |
