What is CVE-2022-0637?

CVE-2022-0637 is a medium-severity open redirect vulnerability in pollbot (pip), affecting versions < 1.4.6. It is fixed in 1.4.6. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.

How severe is CVE-2022-0637?

CVE-2022-0637 has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of pollbot are affected by CVE-2022-0637?

pollbot (pip) versions < 1.4.6 is affected.

Is there a fix for CVE-2022-0637?

Yes. CVE-2022-0637 is fixed in 1.4.6. Upgrade to this version or later.

Is CVE-2022-0637 exploitable, and should I be worried?

Whether CVE-2022-0637 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2022-0637 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

open redirect in pollbot

(From https://bugzilla.mozilla.org/show_bug.cgi?id=1753838)

Summary:
There was an open redirection vulnerability in the path of:

https://pollbot.services.mozilla.com/ and https://pollbot.stage.mozaws.net/

Description:
An attacker can redirect anyone to malicious sites.

Steps To Reproduce:
Type in this URL:

https://pollbot.services.mozilla.com/%0a/evil.com/

It redirects to that website

evil.com

evil.com was used as an example but this could be any website. Note, the /%0a/ and trailing / are required.

Impact

Attackers can serve malicious websites that steal passwords or download ransomware to their victims machine due to a redirect and there are a heap of other attack vectors.

Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites. Typical impact: phishing and credential harvesting via a trusted domain.

CVE-2022-0637 has a CVSS score of 6.1 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.4.6); upgrading removes the vulnerable code path.

Affected versions

pollbot (< 1.4.6)

Security releases

pollbot → 1.4.6 (pip)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
