The vulnerability CVE-2026-15677 affects code-projects Online Job Portal version 1.0. It arises from insufficient validation of the txtFile argument in the /JobSeekerInsert.php script, allowing an attacker to perform unrestricted file uploads. This can lead to unauthorized file placement on the server, potentially enabling further attacks. The vulnerability is remotely exploitable without any privileges or user interaction. Although an exploit is publicly available, no official fix or patch has been released as of the publication date.

Successful exploitation allows an unauthenticated remote attacker to upload arbitrary files to the server, which may lead to remote code execution or other malicious activities depending on the server configuration and uploaded file type. The CVSS 4.0 base score is 6.9 (medium), reflecting network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability has low to limited scope and impact metrics, indicating partial impact on confidentiality, integrity, and availability.

No official patch or remediation has been announced by the vendor. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, it is recommended to restrict file upload functionality, implement strict server-side validation of uploaded files, and monitor for suspicious upload activity. Avoid exposing the vulnerable endpoint publicly if possible.
