CVE-2026-24635
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in DevsBlink EduBlink Core edublink-core allows PHP Local File Inclusion.This issue affects EduBlink Core: from n/a through <= 2.0.7.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA Local File Inclusion (LFI) vulnerability in EduBlink Core PHP code allows attackers to manipulate filename parameters in include/require statements to access arbitrary files on the server, potentially revealing sensitive configuration files, source code, or enabling remote code execution via injection of malicious input.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm EduBlink Core installationLocate the application root directory and identify if it is the EduBlink Core PHP application. Check for characteristic files such as index.php, configuration files, or the presence of an 'include' or 'require' directory structure typical to this codebase.Affected if The system is running EduBlink Core PHP application.
-
Identify PHP include/require usageSearch the codebase for include, require, include_once, or require_once statements that accept variable filenames. Use grep or similar tools: grep -r 'include\|require' --include='*.php' .Affected if Dynamic file inclusion using variables is present in the PHP code.
-
Trace user input to file inclusionReview the code flow from user-controllable input (GET, POST, COOKIE parameters) to the include/require statements identified in the previous step. Look for parameters that might control which file gets included.Affected if User-supplied input directly or indirectly reaches the filename parameter of include/require without sanitization.
-
Check for input validationExamine the code around the file inclusion to determine if basename(), pathinfo(), or other sanitization functions are used, and whether allowlist validation exists for included files.Affected if No input validation or allowlisting is implemented on the filename parameter before inclusion.
-
Review server logs for traversal attemptsInspect web server access logs for patterns like '../' or null byte injection in requests that may target file inclusion endpoints.Affected if Log analysis reveals unauthenticated requests with directory traversal sequences targeting PHP inclusion points.
The environment is affected if EduBlink Core PHP is running and user input can reach include/require statements without sanitization, allowing manipulation of filenames to access arbitrary files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and whitelisting for file inclusion paths, use basename() to strip directory traversal sequences, and avoid passing user input directly to include/require statements. Upgrade to a patched version if available.
