CVE Alert: CVE-2026-86276 – SourceCodester – Syllabus-Aligned Learning Management & Examination System

A flaw has been found in SourceCodester Syllabus-Aligned Learning Management & Examination System 1.0. This issue affects some unknown processing of the file db.php. Executing a manipulation can lead to hard-coded credentials. The attack can be executed remotely. The exploit has been published and may be used.

**Risk verdict:** Elevated and actionable risk: publicly available exploit material and unauthenticated remote access warrant prompt remediation, although KEV inclusion, SSVC exploitation status and EPSS are not supplied.

**Why this matters:** Exposed credentials may enable unauthorised access to application or database functions, with consequences including altered learning records, examination content, user data and service availability. The likely attacker objective is opportunistic compromise of internet-facing installations, followed by data manipulation, extortion or use of the host as a foothold.

**Most likely attack path:** AV:N, AC:L, PR:N and UI:N indicate a remote, low-effort path requiring no account or victim interaction; the published PoC materially lowers the barrier for scanning and exploitation. Scope is unchanged, so direct impact appears confined to the application and its host, but credential reuse or a poorly isolated database could enable lateral movement.

**Who is most exposed:** Organisations running this freeware application on publicly reachable PHP/web servers, particularly small schools, training providers and test environments with default configurations. Internet-facing deployments with shared database credentials or excessive service-account privileges are highest risk.

Review web logs for unusual requests to the affected PHP endpoint and repeated probing.

Hunt for authentication using embedded or application service credentials from unfamiliar hosts.

Check database audit logs for unexpected reads, writes, account changes or schema access.

Look for new web files, scheduled tasks or outbound connections from the application server.

Mitigation and prioritisation:

Apply a vendor-supported fix or remove the affected component; otherwise patch or replace the application urgently.

Rotate exposed credentials, use unique secrets and restrict database privileges.

Remove internet exposure behind VPN or an access gateway and enforce network segmentation.

Validate changes in staging, preserve evidence, and review connected accounts for reuse.
