CVE-2026-110748
Description
A flaw was found in Apache SIS. When processing data files containing links to external resources, the application opens referenced files without validating or restricting their paths. An attacker could exploit this by supplying a specially crafted data file containing arbitrary local file paths, potentially leading to unauthorized file access or information disclosure.
Statement
This vulnerability is rated as Low severity because successful exploitation requires local ingestion of untrusted geospatial datasets, and the parsing engine strictly terminates when encountering unexpected file schemas, which substantially hinders sensitive data exfiltration. Apache SIS is not included in standard Red Hat Enterprise Linux runtime environments or core product offerings, appearing primarily as an optional third-party dependency in custom GIS application stacks. Consequently, Red Hat systems are not exposed by default, and any risk is confined to specialized applications configured to parse unverified external spatial markup.
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 to 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.
