GraphQL-core: Denial Of Service Via Comment Tokens Bypassing The Parser's Max_tokens Limit

Summary The parser's "maxtokens" limit — the documented defence against oversized GraphQL documents — did not count comment tokens. A document padded with comments could therefore pass a "maxtokens" check of any size while still allocating one "Token" object per comment, all of which stay reachab...

Allocation of Resources Without Limits or Throttling

Overview graphql-core is a GraphQL implementation for Python, a port of GraphQL.js, the JavaScript reference implementation for GraphQL. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the advancelexer function in...

CVE-2026-75508 GraphQL-core: Denial of service via comment tokens bypassing the parser's max_tokens limit

GraphQL-core is a Python port of the GraphQL.js reference implementation. From 3.2.3 until 3.2.12 and 3.3.0rc1, the parser's maxtokens limit in Parser.advancelexer counts only non-comment tokens returned after Lexer.lookahead skips comments. Each skipped comment is still allocated as a Token and...

CVE-2026-75508

The GraphQL-core Python library (versions 3.2.3 through 3.2.12 and 3.3.0rc1 ) is vulnerable to a Denial of Service via memory exhaustion. The root cause is that the max_tokens limit in Parser.advance_lexer only counts non-comment tokens, while Lexer.lookahead() still allocates and retains Token o...

GraphQL Python GraphQL-core 3 resource management error vulnerability

In GraphQL Python, there is a resource management error vulnerability in versions 3.2.3 through 3.2.12 and 3.3.0a3 through 3.3.0rc1. This vulnerability arises because the parser’s maxtokens limit only counts non-comment tokens; however, comments that are skipped are still assigned as Tokens via...
