CVE-2026-75758 is an uncontrolled recursion vulnerability in the Elixir standard library affecting functions inspect/1, List.to_string/1, and List.to_charlist/1. It occurs when a specially crafted list with a printable prefix exceeding 4096 elements but containing invalid elements later causes repeated nested inspections, leading to process stack growth and potential memory exhaustion of the BEAM node. This vulnerability affects specific release candidate and stable versions of Elixir from 1.15.0-rc.0 up to but not including 1.18.5, 1.19.0-rc.0 up to but not including 1.19.6, and 1.20.0-rc.0 up to but not including 1.20.4.

Uncontrolled Resource Consumption vulnerability in the Elixir standard library's Version module allows an attacker who controls a version string to cause a denial of service through CPU and memory exhaustion. The version parser converts numeric version components (major, minor, patch and numeric pre-release/build identifiers) to integers without bounding their length. A single large all-digit component therefore forces a super-linear, non-yielding base-10 to arbitrary-precision integer conversion (String.to_integer/1, i.e. :erlang.binary_to_integer/1) that pins a BEAM scheduler, and a larger component raises an uncaught SystemLimitError that crashes the calling process. A single moderately sized string (around one megabyte) is enough; no authentication is required. This is reachable from the public entry points Version.parse/1, Version.parse!/1, Version.match?/3, Version.compare/2, and Version.parse_requirement/1, which applications routinely call on untrusted input such as HTTP parameters, dependency-manifest fields, and package metadata. This vulnerability is associated with program files lib/version.ex and program routines 'Elixir.Version.Parser':parse_digits/2. This issue affects Elixir: from 1.5.0 before 1.20.1.
