CVE-2026-80227 (GCVE-0-2026-80227)

Vulnerability from cvelistv5 – Published: 2026-08-30 11:53 – Updated: 2026-08-30 11:53

Title

SQL string_trim removes only spaces, diverging from in-memory trimming in AshSql

Summary

Incorrect Comparison vulnerability in ash-project ash_sql allows a user to pad a string field with tab, newline, carriage-return, or form-feed characters and pass a trimmed uniqueness or equality check in the database that the same expression would fail in memory (or the reverse). string_trim/1 compiles to REGEXP_REPLACE patterns built from an Elixir string in which \s is the escape for a single space (codepoint 32), not a regex whitespace class. The generated SQL therefore removes only literal spaces and leaves tabs, newlines, carriage returns, and form feeds in place, whereas String.trim/1 in Elixir removes them all. Any Ash filter, validation, or identity that relies on string_trim/1 then behaves differently depending on whether Ash pushes the expression down to SQL or evaluates it in memory, so padded input can register a near-duplicate value or slip past a trimmed comparison. This issue affects ash_sql: from 0.1.0 before 0.7.1.

      "value": "Incorrect Comparison vulnerability in ash-project ash_sql allows a user to pad a string field with tab, newline, carriage-return, or form-feed characters and pass a trimmed uniqueness or equality check in the database that the same expression would fail in memory (or the reverse).\n\nstring_trim/1 compiles to REGEXP_REPLACE patterns built from an Elixir string in which \\s is the escape for a single space (codepoint 32), not a regex whitespace class. The generated SQL therefore removes only literal spaces and leaves tabs, newlines, carriage returns, and form feeds in place, whereas String.trim/1 in Elixir removes them all. Any Ash filter, validation, or identity that relies on string_trim/1 then behaves differently depending on whether Ash pushes the expression down to SQL or evaluates it in memory, so padded input can register a near-duplicate value or slip past a trimmed comparison.\n\nThis issue affects ash_sql: from 0.1.0 before 0.7.1."
