Pannellum Cross-Site Scripting due to data not being sanitized for URIs or vbscript

Moderate severity GitHub Reviewed Published Nov 22, 2019 in mpetroff/pannellum • Updated Jan 11, 2023

Package

npm pannellum (npm)

Affected versions

>= 2.5.0, < 2.5.5

Patched versions

2.5.5

Description

Versions of pannellum prior to 2.5.6 are vulnerable to Cross-Site Scripting (XSS). The package fails to sanitize URLs for data URIs, which may allow attackers to execute arbitrary code in a victim's browser.

Recommendation

Upgrade to version 2.5.6 or later.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
