Security readout for executives and security teams
Plain-English summary
CVE-2026-0547 affects PHPGurukul Online Course Registration 3.0 and 3.1. An authenticated remote user may be able to upload unrestricted files through the student profile photo field in the admin edit-student-profile.php page. Public proof-of-concept material is reported, but the provided sources do not show active exploitation or a named vendor fix.
Executive priority
Treat as a near-term remediation item for any exposed deployment. It is not currently evidenced as actively exploited, but public exploit availability and upload risk justify prompt validation, access restriction, and vendor follow-up.
Technical view
The issue is reported in /admin/edit-student-profile.php, component Student Registration Page, where manipulation of the photo argument can cause unrestricted upload. The CVSS v2 score is 6.5 with network access, low complexity, and single authentication required. Mapped weaknesses include CWE-434 and CWE-284. Exploit availability is public per VulDB/CVE data.
Likely exposure
Exposure is likely limited to deployments of PHPGurukul Online Course Registration versions 3.0 or 3.1 where authenticated users can reach the admin student profile editing workflow. Internet-facing admin panels raise risk. The sources do not identify other affected products or versions.
Exploitation context
The vulnerability is remotely reachable but requires authentication according to the CVSS vector. Public exploit or proof-of-concept material is referenced, increasing likelihood of testing by attackers. It is not listed as KEV in the provided bundle, and no cited source confirms active exploitation.
Researcher notes
Evidence is based on CVE/VulDB-style reporting. The bundle names unrestricted upload for edit-student-profile.php, while one linked GitHub reference appears titled for cross-site scripting, so validate primary details against vendor or VulDB records. No patch level, fixed version, or official advisory is provided in the sources.
Mitigation direction
- Inventory PHPGurukul Online Course Registration deployments and confirm versions.
- Restrict access to administrative pages to trusted networks or VPN users.
- Review vendor guidance for updates or patches; none are named in provided sources.
- Temporarily limit or disable profile photo uploads if operationally feasible.
- Ensure uploaded files cannot execute as server-side code.
Validation and detection
- Confirm whether versions 3.0 or 3.1 are deployed.
- Check whether /admin/edit-student-profile.php is reachable from untrusted networks.
- Review application roles that can modify student profile photos.
- Inspect upload handling controls for file type, storage path, and execution restrictions.
- Review web logs for unusual upload activity on the affected endpoint.
