result = subprocess.run([sys.executable, str(builder), str(content), str(main)], - OBFUSCATION_ENCODED_BLOB Medium
Contains a long base64 shaped string in a file that should be readable.
html_mcp_web/static/ace/ace.js, line 1
(function(){function o(n){var i=e;n&&(e[n]||(e[n]={}),i=e[n]);if(!i.define||!i.define.packaged)t.original=i.define,i.define=t,i.define.packaged=!0;if(!i.require||!i.require.package - OBFUSCATION_MINIFIED_PAYLOAD Medium
Contains a very long line with almost no spaces in a script or style file.

(function(){function o(n){var i=e;n&&(e[n]||(e[n]={}),i=e[n]);if(!i.define||!i.define.packaged)t.original=i.define,i.define=t,i.define.packaged=!0;if(!i.require||!i.require.package
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
