Security

• Upgraded js-yaml to 3.14.2 and 4.1.1 to mitigate CVE-2025-64718
• Upgraded glob to 10.5.0 to mitigate CVE-2025-64756
• Upgraded langchain-core to 0.3.80 to mitigate CVE-2025-65106

To fix the problem, the dot (.) in the regular expression should be properly escaped. In JS string literals intended as regex patterns, you must use a double backslash (\\.) so that when passed to a regex engine, the pattern matches a literal dot rather than any character. Specifically, in the definition of MULTIMODAL_FILENAME_PATTERN on line 410 of source/infrastructure/lib/utils/constants.ts, the .(${SUPPORTED_MULTIMODAL_FILE_EXTENSIONS.join('|')}) should be changed to \\. so the final regex, when interpreted, will correctly match file extensions separated by a dot.

No new methods, types, or imports are needed; simply change \. to \\. in the template literal.

To fix the problem, ensure that when building a regular expression string intended to match a literal . (dot), the dot is escaped twice in the string: once for the string itself and once for the RegExp, i.e., \\.. You only need to edit the line assigning MULTIMODAL_FILENAME_PATTERN in source/ui-chat/src/utils/constants.ts: change \. to \\.. No changes to imports or definitions are needed, as only the string literal must be updated.
