Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Spencer14420/sp php email handler, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Messages sent using this script are vulnerable to abuse, as the script allows anybody to specify arbitrary email recipients and include user-provided content in confirmation emails. This could enable malicious actors to use your server to send spam, phishing emails, or other malicious content, potentially damaging your domain's reputation and leading to blacklisting by email providers. ### Patches Patched in version 1.0.0 by removing user-provided content from confirmation emails. All pre-release versions (alpha and beta) are vulnerable to this issue and should not be used. ### Workarounds There are no workarounds for this issue. Users must upgrade to version 1.0.0 to mitigate the vulnerability.
