Elevated risk56th percentile - higher than 56% of all known CVEs
Summary
Pathway through 0.31.1 (fixed in commit d09722e) allows a remote unauthenticated attacker to cause a denial of service by sending a short glob pattern with many ** tokens to the /v1/retrieve, /v1/inputs, or /v2/answer HTTP endpoints. The recursive matcher without memoization leads to exponential time complexity, consuming CPU for tens of seconds per request.
Risk Assessment
The organization is at risk of denial of service (DoS) – a few requests from an unauthenticated attacker can crash the Pathway system, blocking access to document processing and responses.
Recommendation
Immediately update Pathway to a version containing commit d09722e or later. If updating is not possible, restrict access to the /v1/retrieve, /v1/inputs, and /v2/answer endpoints to trusted IPs or use a WAF to block patterns with multiple ** tokens.

GV-Face transmits sensitive user credentials and related authentication data over unencrypted HTTP connections. The HTTP traffic is not encrypted, allowing an attacker to intercept it.
- CVE-2026-120017Critical
SAP NetWeaver AS ABAP and ABAP Platform do not sufficiently verify incoming authentication assertions under certain configurations. An unauthenticated attacker could submit crafted data to bypass authentication and impersonate arbitrary users, including privileged accounts.
Original NVD description (English source)
Pathway through 0.31.1, fixed in commit d09722e, document store applies a caller-supplied glob pattern to indexed document paths using a hand-written recursive matcher that branches two ways on each ** token without memoization, giving exponential worst-case complexity. The filepath_globpattern value is taken from the body of the unauthenticated HTTP endpoints /v1/retrieve, /v1/inputs and /v2/answer and compiled into a filter evaluated once per indexed document, with no length or **-count limit. A remote unauthenticated attacker can submit a short pattern containing many ** tokens to consume CPU for tens of seconds per request, and a small number of requests denies service.
