CVE-2026-59094: Inefficient Algorithmic Complexity in pathwaycom pathway
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.
AI Analysis
Technical Summary
The vulnerability in pathwaycom pathway (up to version 0.31.1) arises from a hand-written recursive glob pattern matcher used in the document store. This matcher branches two ways on each '**' token without memoization, leading to exponential worst-case time complexity. The vulnerable endpoints (/v1/retrieve, /v1/inputs, /v2/answer) accept unauthenticated HTTP requests containing a filepath_globpattern value that is compiled into a filter evaluated once per indexed document. Attackers can exploit this by submitting short patterns with many '**' tokens, causing CPU consumption for tens of seconds per request and enabling denial of service with a small number of requests. The issue is fixed in commit d09722e, but no official patch or vendor advisory is provided in the data.
Potential Impact
This vulnerability allows remote unauthenticated attackers to cause denial of service by submitting crafted glob patterns that trigger exponential CPU usage in the document store's pattern matching. This can degrade or completely disrupt service availability for legitimate users. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. The vulnerability is fixed in commit d09722e, so applying this fix or upgrading beyond version 0.31.1 is recommended once official patches are available. Until then, consider restricting access to the affected endpoints or implementing rate limiting to mitigate denial of service risk.
