5 Security Vulnerabilities
Rails Active Support has a possible DoS vulnerability in its number helpers

Impact
Active Support number helpers accept strings containing scientific notation (e.g. 1e10000), which when converted to a string could be expanded into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability.

The fixed releases are available at the normal locations.

Rails Active Support has a possible XSS vulnerability in SafeBuffer#%

Impact
SafeBuffer#% does not propagate the @html_unsafe flag to the newly created buffer. If a SafeBuffer is mutated in place (e.g. via gsub!) and then formatted with % using untrusted arguments, the result incorrectly reports html_safe? == true, bypassing ERB auto-escaping and possibly leading to XSS.

There is a possible file disclosure of locally encrypted files in Active Support. This vulnerability has been assigned the CVE identifier CVE-2023-38037.
Versions Affected: >= 5.2.0 Not affected: < 5.2.0 Fixed Versions: 7.0.7.1, 6.1.7.5
Impact
ActiveSupport::EncryptedFile writes contents that will be encrypted to a temporary file. The temporary file’s permissions are defaulted to the user’s current umask settings, meaning that it’s possible for other users on the same system to read the contents of the temporary file.
Attackers that have access to the file system could possibly read the contents of this temporary file while a user is editing it.
All users running an affected release should either upgrade or use one of the workarounds immediately.
Releases
The fixed releases are available at the normal locations.
Workarounds
To work around this issue, you can set your umask to be more restrictive like this:
$ umask 0077

Possible File Disclosure of Locally Encrypted Files
Published date: 2023-08-23
Framework: rails
CVE: 2023-38037
CVSS V3: 5.5
There is a possible file disclosure of locally encrypted files in Active Support. This vulnerability has been assigned the CVE identifier CVE-2023-38037.
- Versions Affected: >= 5.2.0
- Not affected: < 5.2.0
- Fixed Versions: 7.0.7.1, 6.1.7.5
Impact
ActiveSupport::EncryptedFile writes contents that will be encrypted to a temporary file. The temporary file’s permissions are defaulted to the user’s current umask settings, meaning that it’s possible for other users on the same system to read the contents of the temporary file.
Attackers that have access to the file system could possibly read the contents of this temporary file while a user is editing it.
All users running an affected release should either upgrade or use one of the workarounds immediately.
Releases
The fixed releases are available at the normal locations.
