Which packages are affected by CVE-2026-2469?

CVE-2026-2469 affects the following packages: directorytree/imapengine (Packagist). Ecosystems affected: Packagist.

How do I fix CVE-2026-2469?

Update directorytree/imapengine to 1.22.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-2469 is resolved across your whole dependency graph.

How do I detect CVE-2026-2469 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for directorytree/imapengine. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2026-2469 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2026-2469?

O3 pinpoints whether CVE-2026-2469 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-2469 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-2469 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-2469?

CVE-2026-2469 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 27th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-2469?

CVE-2026-2469 is classified as CWE-74 (CWE-74). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

Versions of the package directorytree/imapengine before 1.22.3 are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') via the id() function in ImapConnection.php due to improperly escaping user input before including it in IMAP ID commands. This allows attackers to read or delete victim's emails, terminate the victim's session or execute any valid IMAP command on victim's mailbox by including quote characters " or CRLF sequences \r\n in the input.
