Attackers who know the victim's Elio process ID can plant a symlink so previewing media, fonts or archives truncates and overwrites victim-owned files.","cvssScore":4.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:N","cwes":["CWE-377"],"vendors":[],"products":[],"references":[{"url":"https://github.com/elio-fm/elio/blob/e7daae44ce748310de441499576bdc31b936d54c/src/preview/archives/external_tools.rs#L30-L45","tags":[]},{"url":"https://github.com/elio-fm/elio/blob/e7daae44ce748310de441499576bdc31b936d54c/src/preview/external_commands.rs#L14-L47","tags":[]},{"url":"https://github.com/elio-fm/elio/blob/e7daae44ce748310de441499576bdc31b936d54c/src/preview/external_commands.rs#L92-L95","tags":[]},{"url":"https://github.com/elio-fm/elio/releases/tag/v1.13.0","tags":[]},{"url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/r1d_wQojfg","tags":[]},{"url":"https://www.vulncheck.com/advisories/elio-through-1.13.0-insecure-temporary-file-creation-in-external-preview-command-capture","tags":[]}],"exploitRefs":[{"url":"https://github.com/elio-fm/elio/blob/e7daae44ce748310de441499576bdc31b936d54c/src/preview/archives/external_tools.rs#L30-L45","tags":[]},{"url":"https://github.com/elio-fm/elio/blob/e7daae44ce748310de441499576bdc31b936d54c/src/preview/external_commands.rs#L14-L47","tags":[]},{"url":"https://github.com/elio-fm/elio/blob/e7daae44ce748310de441499576bdc31b936d54c/src/preview/external_commands.rs#L92-L95","tags":[]},{"url":"https://github.com/elio-fm/elio/releases/tag/v1.13.0","tags":[]}],"hasPoc":true,"ai":null}
