CVE-2026-48099
Description
A flaw was found in WsgiDAV, a WebDAV server. A remote attacker could exploit this vulnerability by sending a specially crafted WebDAV request path containing encoded parent-directory segments. This could allow the attacker to escape the configured filesystem share root, potentially leading to unauthorized access to sensitive files or directories outside the intended scope.
Statement
Red Hat products do not ship WsgiDAV. The component is present only in the community python-wsgidav packages for Fedora and EPEL, both of which ship version 4.3.5 — at or above the upstream fixed release 4.3.4 (the vulnerable range is all versions up to and including 4.3.3). The vulnerable code path is therefore not present in any Red Hat-shipped build, and no Red Hat product is affected by this flaw.
Mitigation
No mitigation is required. Red Hat products are not affected by this vulnerability.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
The attacker may be able to create or overwrite critical files that are used to execute code, such as programs or libraries.
Integrity
Technical Impact: Modify Files or Directories
The attacker may be able to overwrite or create critical files, such as programs, libraries, or important data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, appending a new account at the end of a password file may allow an attacker to bypass authentication.
Confidentiality
Technical Impact: Read Files or Directories
The attacker may be able read the contents of unexpected files and expose sensitive data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, by reading a password file, the attacker could conduct brute force password guessing attacks in order to break into an account on the system.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
The attacker may be able to overwrite, delete, or corrupt unexpected critical files such as programs, libraries, or important data. This may prevent the product from working at all and in the case of protection mechanisms such as authentication, it has the potential to lock out product users.
