Technical Summary
This vulnerability in svgdotjs svg.js up to version 3.2.5 affects the EventTarget.on function, allowing an attacker to improperly modify object prototype attributes. Such prototype pollution can lead to unexpected behavior or security issues in applications using this library. The attack vector is remote with no user interaction required, and the vulnerability has a CVSS 4.0 base score of 5.3 (medium severity). The vendor has been informed but has not yet provided a remediation or patch.
Potential Impact
An attacker with low privileges can remotely exploit this vulnerability to manipulate object prototype attributes within applications using affected versions of svg.js. This may cause application instability or enable further attacks depending on the context in which the library is used. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
