{"id":"AZL-89672","summary":"CVE-2026-49762 affecting package elixir for versions less than 1.16.1-2","details":"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.\n\nThe 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.\n\nThis 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.\n\nThis vulnerability is associated with program files lib/version.ex and program routines 'Elixir.Version.Parser':parse_digits/2.\n\nThis issue affects Elixir: from 1.5.0 before 1.20.1.","modified":"2026-08-29T05:27:27Z","published":"2026-06-09T14:16:44Z","upstream":["CVE-2026-49762"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49762"}],"affected":[{"package":{"name":"elixir","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/elixir"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.16.1-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-89672.json"}}],"schema_version":"1.9.0"}
