CVE-2026-55178: GeoLens: Cross-dataset authorization bypass discloses private dataset metadata, schema, sample values, table rows, and raster/vector tile data

Multiple GeoLens read/link endpoints authorized only the resource named in the request URL (a map, a VRT, a source dataset, an AI request) and failed to re-authorize a second, caller-influenced dataset that the request reached through a relationship, layer reference, mosaic source, or request body. This “authorize the URL resource, read a different dataset un-re-authorized” pattern let callers read data from datasets they have no access to.

The most severe instances require no authentication at all (anonymous, network-only). Others require only the default editor role that any self-service signup / upload user receives.

All issues are fixed in 1.2.3. There is no complete configuration workaround — upgrading is the only full remediation.
