This issue can occur through facts used in the template if the user is trying to put templates in multi-line YAML strings and the facts being handled do not routinely include special template characters. This flaw allows attackers to perform command injection, which discloses sensitive information. The highest threat from this vulnerability is to confidentiality and integrity. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | ansible | 26.04 LTS resolute | Vulnerable | | 25.10 questing | Ignored end of life, was needed | | 25.04 plucky | Ignored end of life, was needed | | 24.10 oracular | Ignored end of life, was needed | | 24.04 LTS noble | Vulnerable | | 23.10 mantic | Ignored end of life, was needed | | 23.04 lunar | Ignored end of life, was needed | | 22.10 kinetic | Ignored end of life, was needed | | 22.04 LTS jammy | Fixed 2.10.7+merged+base+2.10.8+dfsg-1ubuntu0.1~esm1 Ubuntu Pro | | 21.10 impish | Ignored end of life | | 21.04 hirsute | Ignored end of life | | 20.10 groovy | Ignored end of life | | 20.04 LTS focal | Fixed 2.9.6+dfsg-1ubuntu0.1~esm1 Ubuntu Pro | | 18.04 LTS bionic | Fixed 2.5.1+dfsg-1ubuntu0.1+esm1 Ubuntu Pro | | 16.04 LTS xenial | Fixed 2.0.0.2-2ubuntu1.3+esm1 Ubuntu Pro | | 14.04 LTS trusty | Not affected | | ansible-base | 26.04 LTS resolute | Not in release | | 25.10 questing | Not in release | | 25.04 plucky | Not in release | | 24.10 oracular | Not in release | | 24.04 LTS noble | Not in release | | 23.10 mantic | Not in release | | 23.04 lunar | Not in release | | 22.10 kinetic | Not in release | | 22.04 LTS jammy | Not in release | | 21.10 impish | Ignored end of life | | 21.04 hirsute | Ignored end of life | | 20.10 groovy | Not in release | | 20.04 LTS focal | Not in release | | 18.04 LTS bionic | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | | ansible-core | 26.04 LTS resolute | Not affected | | 25.10 questing | Not affected | | 25.04 plucky | Not affected | | 24.10 oracular | Not affected | | 24.04 LTS noble | Not affected | | 23.10 mantic | Not affected | | 23.04 lunar | Not affected | | 22.10 kinetic | Not affected | | 22.04 LTS jammy | Not affected | | 21.10 impish | Not in release | | 21.04 hirsute | Not in release | | 20.10 groovy | Not in release | | 20.04 LTS focal | Not in release | | 18.04 LTS bionic | Not in release | | 16.04 LTS xenial | Not in release | | 14.04 LTS trusty | Not in release | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) * [Patch details](https://ubuntu.com/security/CVE-2021-3583?format=md#patch-details) ### Get expanded security coverage with Ubuntu Pro Reduce your average CVE exposure time from 98 days to 1 day with expanded CVE patching, ten-years security maintenance and optional support for the full stack of open-source applications.
