[Security] Bump yard from 0.9.12 to 0.9.26

[dependabot-preview]

Bumps yard from 0.9.12 to 0.9.26. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Arbitrary path traversal and file access via yard server A path traversal vulnerability was discovered in YARD <= 0.9.19 when using yard server to serve documentation. This bug would allow unsanitized HTTP requests to access arbitrary files on the machine of a yard server host under certain conditions.

The issue is resolved in v0.9.20 and later.

Patched versions: >= 0.9.20 Unaffected versions: none

Sourced from The GitHub Security Advisory Database.

Moderate severity vulnerability that affects yard

Possible arbitrary path traversal and file access via yard server

Impact

A path traversal vulnerability was discovered in YARD <= 0.9.19 when using yard server to serve documentation. This bug would allow unsanitized HTTP requests to access arbitrary files on the machine of a yard server host under certain conditions.

Thanks to CuongMX from Viettel Cyber Security for discovering this vulnerability.

Patches

Please upgrade to YARD v0.9.20 immediately if you are relying on yard server to host documentation in any untrusted environments.

Workarounds

For users who cannot upgrade, it is possible to perform path sanitization of HTTP requests at your webserver level. WEBrick, for example, can perform such sanitization by default (which you can use via yard server -s webrick), as can certain rules in your webserver configuration.

Affected versions: < 0.9.20
