- 1. Removed manual base64 encoding and st.markdown with unsafe_allow_html=True. 2. Replaced with st.file_uploader and st.image, which handle content safely and escape HTML. 3. Restricted upload to common image file extensions to prevent arbitrary file reads. - Confidence: HIGH - Breaking changes: No
- 1. Added bleach to sanitize uploaded content, removing disallowed tags and attributes. 2. Defined a strict allowlist of tags and attributes to prevent injection of scripts or harmful HTML. 3. Continued using st.markdown with unsafe_allow_html=True only after sanitization. - Confidence: HIGH - Breaking changes: No
- 1. Introduced URL validation using urllib.parse to enforce http/https schemes. 2. Implemented is_private_address() to detect and block requests to private or loopback IP ranges. 3.
