Summary

This repository has a high vulnerability score of 103.0, which means there are many insecure coding patterns that an attacker could exploit to break into the system or steal data. While the malicious-pattern score is very low at 1.0, suggesting the code does not appear to be intentionally harmful, the high vulnerability score indicates that the code contains common mistakes like using weak passwords and executing commands with user input. The scan also found several medium-risk issues, such as potential cross-site scripting vulnerabilities and overly permissive security headers, which could allow attackers to bypass protections or inject malicious scripts into the application. Although some findings are flagged as potentially malicious by automated tools, most of them stem from standard insecure practices rather than deliberate attacks, so they should be addressed through careful code review and updates to fix the underlying weaknesses before deploying the software.

Written by a language model running locally on the scanning machine, from the findings in this report. The risk levels above and below were decided by the scoring model, not by this summary.

Risk, by type

MalDet scores two different questions separately, because they call for different responses: code can be badly written without being hostile, and hostile code is not always badly written.

Vulnerability
High (103)
Insecure coding an attacker could exploit. Usually mistakes, and usually fixable in place.
Malicious pattern
Low (1)
Signs the code may be trying to do harm: hidden payloads, credential access, persistence, exfiltration.

28 of 108 findings were rated more likely genuine than noise by the classifier.

Evidence

Identical findings are grouped, so a single rule firing many times takes one row. Ordered worst first. “Seen” is how many times that finding occurred.

SeverityDetectorFindingSeenExample location
high semgrep bcrypt hash detected 1 /app/Utils/passwordUtil.php:33
high semgrep Executing non-constant commands. This can lead to command injection. 2 /lib/phpmailer/phpmailer/src/PHPMailer.php:1969
high semgrep Evaluating non-constant commands. This can lead to command injection. 1 /cli/i18n/I18nFile.php:85
high yara YARA rule matched: detect_download_and_execute — Downloads a remote resource AND executes it - the actually dangerous combination, not just downloading alone 4 /.github/workflows/tests.yml
high yara YARA rule matched: detect_obfuscated_string_execution — Reconstructs a string character-by-character or from hex escapes, then immediately executes it - fromCharCode/chr() alone are common in ordinary text-processing code, so this requires both the reconstruction and an execution call together 2 /app/Utils/httpUtil.php
high yara YARA rule matched: detect_persistence_mechanism — Modifies a startup/scheduling location - legitimate application code essentially never does this 8 /Docker/entrypoint.sh
medium semgrep File name based on user input risks server-side request forgery. 14 /p/f.php:69
medium semgrep Make sure comparisons involving md5 values are strict (use `===` not `==`) to avoid type juggling issues 12 /app/Utils/dotNotationUtil.php:225
medium semgrep Access-Control-Allow-Origin response header is set to "*". This will disable CORS Same Origin Policy restrictions. 2 /p/api/greader.php:1091
medium semgrep Detection of insertAdjacentHTML from non-constant definition. This can inadvertently expose users to cross-site scripting (XSS) attacks if this comes from user-provided input. If you have to use insertAdjacentHTML, consider using a sanitization library such as DOMPurify to sanitize your HTML. 7 /p/scripts/main.js:1834
medium semgrep Calling `unserialize()` with user input in the pattern can lead to arbitrary code execution. Consider using JSON or structured data approaches (e.g. Google Protocol Buffers). 6 /lib/simplepie/simplepie/src/Cache/File.php:88
medium semgrep Using user input when deleting files with `unlink()` is potentially dangerous. A malicious actor could use this to modify or access files they have no right to. 37 /app/Models/FormAuth.php:92
