Is CodeColorer Safe to Use in 2026?
Mostly Safe
Score 73/100CodeColorer is generally safe to use. 2 past CVEs were resolved. Keep it updated.
The "codecolorer" plugin, version 0.11.0, exhibits a mixed security posture. On the positive side, the static analysis reveals an extremely small attack surface with no apparent AJAX handlers, REST API routes, shortcodes, or cron events. The code also demonstrates good practices regarding SQL queries, exclusively using prepared statements, and generally strong output escaping (93%). Nonce and capability checks are present, indicating some security awareness in the development. However, the presence of one unpatched high-severity vulnerability, identified as Cross-Site Scripting, is a significant concern. This historical pattern of vulnerabilities, particularly XSS, suggests potential weaknesses in input sanitization or output encoding for certain edge cases that have been exploited in the past.
While the current static analysis doesn't flag critical taint flows or dangerous functions, the existence of past XSS vulnerabilities, coupled with the fact that one remains unpatched, points to a residual risk. The single file operation, though not inherently dangerous, warrants a quick review to ensure it's not a vector for further issues. The inclusion of TinyMCE as a bundled library, if not kept up-to-date by the plugin author, could also introduce risks, although this is not explicitly flagged as an issue in the provided data. Overall, the plugin has strengths in its limited attack surface and prepared SQL, but the unpatched XSS vulnerability is a clear and present danger that overshadows these positives.
Key Concerns
- Unpatched high-severity CVE
- Known XSS vulnerability history
- Bundled library (TinyMCE)
