Matched remediation archetype

XML external entity and unsafe XML processing

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

• Inventory XML parsers used by APIs, file imports, office or image formats, identity protocols, feeds, and background jobs.
• Determine whether document type declarations, external entities, XInclude, schemas, or network resolvers are enabled.
• Map parser filesystem and network access and the sensitivity of documents it processes.

Remediate safely

• Configure each parser to reject document type declarations and disable external entity, XInclude, and network resolution features.
• Prefer a data format or hardened parser that does not support external resolution, and apply input size and depth limits.
• Update affected XML libraries and centralize secure parser construction so callers cannot silently override it.
