Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1286: Improper Validation of Syntactic Correctness of Input, where the product receives input that is expected to be well-formed - i.e., to comply with a certain syntax - but it does not validate or incorrectly validates that the input complies with the syntax. In Github.com/nyaruka/phonenumbers, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of the package github.com/nyaruka/phonenumbers before 1.2.2 are vulnerable to Improper Validation of Syntactic Correctness of Input in the phonenumbers.Parse() function. An attacker can cause a panic by providing crafted input causing a "runtime error: slice bounds out of range".
