# Security digest: August 12, 2021

1 editorial brief.

## Take stock

- Check exposure: Jira CVE-2021-26086: 2021 File-Read Bug Added to KEV in 2024 . Anyone still running Jira Server or Data Center older than 8.5.14, 8.13.6 or 8.16.1, especially if it is reachable from the internet.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Check exposure** [Jira CVE-2021-26086: 2021 File-Read Bug Added to KEV in 2024](https://erroneo.us/security/briefs/jira-cve-2021-26086-path-traversal-file-read/index.md): The bug itself only leaks files, and any Jira from the last four years is fixed; the real job is to find any Jira 8.x this old still answering on the network and upgrade or retire it.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
