Arcgis Server

Unauthenticated file disclosure in Esri ArcGIS Server (all versions 12.0 and prior) lets remote attackers read sensitive files by supplying crafted path parameters that escape the intended directory. The flaw is network-reachable with no authentication or user interaction and, per CISA's SSVC framework, is automatable with total technical impact, though no public exploit has been identified and EPSS exploitation probability remains modest at 0.72%. Esri disclosed and patched the issue in its May 2026 ArcGIS security bulletin.

Unrestricted file upload in Esri ArcGIS Server (all versions through 12.0) lets a remote, unauthenticated attacker push arbitrary files to an exposed administrative/upload endpoint, per CVSS PR:N. Esri self-reported the flaw (CWE-434) and rates it critical (CVSS 9.8), and successful upload of an executable payload can lead to full server compromise. There is no public exploit identified at time of analysis, and EPSS is low (0.22%, 13th percentile), indicating it is not yet a mass-exploitation target.

Improper authentication on an undocumented administrative endpoint in ArcGIS Server 11.1 through 12.0 allows unauthenticated remote attackers to disrupt the web-based browsing interface by sending a crafted HTTP request. The vulnerability is classified as CWE-287 and carries a CVSS 5.3 medium score, reflecting network-reachable, zero-privilege exploitation offset by limited impact (integrity only, no confidentiality or availability loss). No public exploit identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
