CVE-2026-32700 is a medium-severity race condition vulnerability in devise (rubygems), affecting versions <= 5.0.2. It is fixed in 5.0.3.
Impact A race condition in Devise's Confirmable module allows an attacker to confirm an email address they do not own. This affects any Devise application using the reconfirmable option (the default when using Confirmable with email changes). By sending two concurrent email change requests, an attacker can desynchronize the confirmationtoken and unconfirmedemail fields. The confirmation token is sent to an email the attacker controls, but the unconfirmedemail in the database points to a victim's email address. When the attacker uses the token, the victim's email is confirmed on the attacker's account. Patches This is patched in Devise v5.0.3. Users should upgrade as soon as possible. Workarounds Applications can override this specific method from Devise models to force unconfirmedemail to be persisted when unchanged: (assuming your model is User) Note: Mongoid does not seem to respect that willchange! should force the attribute to be persisted, even if it did not really change, so you might have to implement a workaround similar to Devise by setting changedattributes["unconfirmed_email"] = nil as well.
Multiple concurrent operations access a shared resource without proper synchronization, producing unpredictable results depending on timing. Typical impact: TOCTOU exploits, data corruption, or privilege escalation.
CVE-2026-32700 has a CVSS score of 5.3 (Medium). The vector is network-reachable, low privileges required, and no user interaction. 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 (5.0.3). Upgrading removes the vulnerable code path.
rubygems
devise (<= 5.0.2)devise → 5.0.3 (rubygems)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 instead of chasing every advisory.
Kodem's runtime-powered SCA identifies whether CVE-2026-32700 is reachable in your applications. Explore open-source security for your team.

CVE-2026-32700 has a CVSS score of 5.3 (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.
devise (rubygems) versions <= 5.0.2 is affected.
Yes. CVE-2026-32700 is fixed in 5.0.3. Upgrade to this version or later.
Whether CVE-2026-32700 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.

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.
Upgrade devise to 5.0.3 or later.
