Dear Esteemed Developer, 👩💻👨💻 My name is Hongseo Jang, a software developer specializing in security solutions based in South Korea. 🇰🇷 We have developed a security software called Autofic, which analyzes user repositories to detect security vulnerabilities using SAST tools, and automatically applies code fixes through an LLM-based model. 🛡️🤖 During an analysis of your repository, we identified certain security vulnerabilities. We have submitted a Pull Request containing the automatically generated fixes via Autofic. If you have any questions or require further information, please feel free to contact us at the email address below: Thank you for your time and consideration. |
🔧 About This Pull Request
This patch was automatically created by AutoFiC,
an open-source framework that combines static analysis tools with AI-driven remediation.
Using Semgrep, CodeQL, and Snyk Code, AutoFiC detected potential security flaws and applied verified fixes.
Each patch includes contextual explanations powered by a large language model to support review and decision-making.

src/data/DeviceModels.js🧩 SAST Analysis Summary
📝 LLM Analysis
🔸 Vulnerability Description
The code contains a vulnerability related to incomplete sanitization. Specifically, the
getKeyfunction only replaces the first occurrence of '\' in the given pattern, which can lead to potential security issues such as improper handling of escape characters.🔸 Recommended Fix
Modify the
getKeyfunction to replace all occurrences of '\' in the pattern, ensuring complete sanitization.🔸 Additional Notes
The fix ensures that all occurrences of the backslash character are replaced, providing better sanitization and reducing the risk of security vulnerabilities associated with improper input handling.

📝 LLM Analysis
🔸 Vulnerability Description
The regular expression used in line 844 may cause exponential backtracking, leading to a Regular Expression Denial of Service (ReDoS) vulnerability. This occurs when processing strings starting with '(FOMA ' and containing many repetitions of ':'.
🔸 Recommended Fix
Simplify the regular expression to avoid patterns that cause exponential backtracking. Specifically, ensure that the pattern does not attempt to match nested or repeated structures that can lead to excessive backtracking.
🔸 Additional Notes
The regular expression was simplified to prevent potential ReDoS attacks by avoiding complex nested structures that can lead to excessive backtracking. This change ensures that the pattern remains efficient and secure.
🛠 Fix Summary
All identified vulnerabilities have been remediated following security best practices such as parameterized queries and proper input validation. Please refer to the diff tab for detailed code changes.
