MITRE ATT&CK
2 techniques across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires (1) a valid Pagekit account with at least low-level privileges sufficient to reach the file-upload functionality associated with /storage/poc.php, and (2) the ability to upload a file whose type/extension is not properly validated so that a PHP payload can be stored and subsequently executed by the web server. Limiting factors: authentication is mandatory (PR:L), so fully anonymous exploitation is not supported by the CVSS vector; the target must be running the specific affected build Pagekit 1.0.18 and must serve/execute files from the upload location. No user interaction is required (UI:N). |
| Impact | Signals are mixed and point to a serious-but-not-emergency issue. The input CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C) scores 9.9 Critical, reflecting network-reachable, low-complexity exploitation requiring only low-privilege authentication and yielding full confidentiality, integrity, and availability impact with a scope change. Against this, EPSS is only 0.53% (43rd percentile), indicating no observed mass exploitation activity, and the vulnerability is NOT on the CISA KEV list, so there is no confirmed active exploitation. A public POC is referenced (GitHub research repo), which raises practical exploitability above a theory-only flaw. The net picture: a credible, easily-weaponized authenticated RCE with public exploit code, but low real-world exploitation signal so far - consistent with an obscure, lightly-deployed product rather than a mass-targeted one. Two caveats weaken confidence in the raw score: the CVSS claims S:C (scope change), which is generous for a web-app file-upload RCE that executes within the application's own context, and CWE-78 (OS Command Injection) does not match the described weakness (arbitrary file upload → code execution, i.e. CWE-434). Prioritize patching for any internet-exposed Pagekit 1.0.18 instance where untrusted users can authenticate, but this is not a drop-everything KEV-grade emergency. |
| Exploit ScenarioDerived | A low-privileged authenticated user (or an attacker who has obtained any valid account) uploads a crafted PHP file through the /storage/poc.php upload path, which fails to restrict file type or execution. The attacker then requests the uploaded file, causing the web server to execute it and granting arbitrary code execution on the host. A public proof-of-concept for this flaw is available, lowering the skill barrier to exploitation. |

Alert meAnalysisAIv1 – Oct 13, 2026
Authenticated attackers with low privileges can upload a crafted PHP file to Pagekit CMS 1.0.18 via the /storage/poc.php endpoint, leading to remote code execution on the server. Publicly available exploit code exists but no confirmed active exploitation (CISA KEV) is reported; EPSS is low at 0.53%, indicating a serious but not emergency-level threat. The vulnerability requires a valid account and improper file-type validation, and the independently assessed CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base score 8.8) reflects high impact with scope unchanged.
RemediationAI
No vendor-released patch has been identified in the available intelligence. As compensating controls, restrict access to the /storage/poc.php endpoint via web server configuration (e.g., deny all requests to that path) - this may disrupt legitimate administrative functions if the endpoint is used for intended uploads. Additionally, configure the web server to prevent execution of PHP files in upload directories (e.g., disable PHP engine in /storage or set appropriate .htaccess rules), with the trade-off that any legitimate PHP-based features in that directory would stop working. Enforce strict whitelisting of allowed file types for uploads and validate file content, not just extension. Limit the number of accounts with upload privileges, since authentication is required (PR:L). Monitor the Pagekit project and the referenced GitHub repository for an official patch.

Technical ContextAI · show details
Pagekit is a PHP-based content management system built on Symfony components. The /storage/poc.php endpoint likely handles file uploads without adequate validation of file extensions or content, allowing a PHP payload to be stored and later executed by the web server. Although the provided CWE is CWE-78 (OS command injection), the described attack path is more consistent with unrestricted file upload (CWE-434), effectively achieving arbitrary code execution. The CVSS vector indicates network exploitation with low complexity and low privileges required, and no user interaction; the independent assessment assigns scope unchanged (S:U) rather than changed (S:C), yielding a base score of 8.8 instead of the reported 9.9. The CPE cpe:2.3:a:pagekit:pagekit:1.0.18 confirms that only version 1.0.18 is identified as affected in the available intelligence.

DescriptionCVE.org
An authenticated arbitrary file upload vulnerability in the /storage/poc.php component of Pagekit CMS v1.0.18 allows attackers to execute arbitrary code via uploading a crafted PHP file.
Executive ViewAI
A critical remote code execution flaw in Pagekit CMS 1.0.18 allows any user holding a low-privilege account to upload a malicious PHP file and gain full control of the web server, and working exploit code is publicly available even though no vendor patch has been issued. Because Pagekit is typically internet-facing and hosts public content, compromise could expose customer data, deface the site, or provide a beachhead into the internal network. Leadership should treat this as a high-priority remediation item, particularly if Pagekit accounts are broadly provisioned or self-registration is enabled.
No vendor-released patch identified at time of analysis. Interim mitigations: disable PHP execution in the /storage/ upload directory at the web server level; restrict and audit accounts with upload privileges, disabling self-registration and unused accounts; deploy WAF or reverse-proxy rules to block PHP uploads and direct requests to /storage/*.php; monitor the storage directory with file-integrity tooling and alert on new PHP files; review logs for requests to /storage/poc.php; prioritize migration to a supported CMS if no vendor fix is forthcoming.

Attack Technique
OS command injection occurs when an application passes unsanitized user input directly into system shell commands.
Malicious file upload attacks exploit insufficient validation when web applications accept user-provided files.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
