A flaw was found in Apache James's Mime4j TempFileStorageProvider class, where it may set improper permissions when utilizing temporary files. This flaw allows a locally authorized attacker to access information outside their intended permissions.
Similarly to CVE-2024-34055, Apache James is vulnerable to denial of service through the abuse of IMAP literals from both authenticated and unauthenticated users, which could be used to cause unbounded memory allocation and very long computations
Version 3.7.6 and 3.8.2 restrict such illegitimate use of IMAP literals.
Apache James prior to versions 3.8.1 and 3.7.5 is vulnerable to SMTP smuggling.
A lenient behaviour in line delimiter handling might create a difference of interpretation between the sender and the receiver which can be exploited by an attacker to forge an SMTP envelop, allowing for instance to bypass SPF checks.
The patch implies enforcement of CRLF as a line delimiter as part of the DATA transaction.
We recommend James users to upgrade to non vulnerable versions.
Apache James prior to version 3.7.5 and 3.8.0 exposes a JMX endpoint on localhost subject to pre-authentication deserialisation of untrusted data. Given a deserialisation gadjet, this could be leveraged as part of an exploit chain that could result in privilege escalation. Note that by default JMX endpoint is only bound locally.
We recommend users to: - Upgrade to a non-vulnerable Apache James version
- Run Apache James isolated from other processes (docker - dedicated virtual machine) - If possible turn off JMX
Usage of temporary files with insecure permissions by the Apache James server allows an attacker with local access to access private user data in transit.
Vulnerable components includes the SMTP stack and IMAP APPEND command.
This issue affects Apache James server version 3.7.2 and prior versions.
Apache James server version 3.7.3 and earlier provides a JMX management service without authentication by default. This allows privilege escalation by a malicious local user.
Administrators are advised to disable JMX, or set up a JMX password.
Note that version 3.7.4 onward will set up a JMX password automatically for Guice users.
Apache James server JMAP HTML to text plain implementation in versions below 3.8.2 and 3.7.6 is subject to unbounded memory consumption that can result in a denial of service.
Users are recommended to upgrade to version 3.7.6 and 3.8.2, which fix this issue.
Affected versions:
- Apache James server 3.8.0 through 3.8.1 - Apache James server through 3.7.5
Description:
Apache James server JMAP HTML to text plain implementation in versions below 3.8.2 and 3.7.6 is subject to unbounded memory consumption that can result in a denial of service.
Users are recommended to upgrade to version 3.7.6 and 3.8.2, which fix this issue.

Spooler in Apache Foundation James 2.2.0 allows local users to cause a denial of service (memory consumption) by triggering various error conditions in the retrieve function, which prevents a lock from being released and causes a memory leak.
The SMTP server in Apache Java Mail Enterprise Server (aka Apache James) 2.2.0 allows remote attackers to cause a denial of service (CPU consumption) via a long argument to the MAIL command.
Apache James Server 2.3.2, when configured with file-based user repositories, allows attackers to execute arbitrary system commands via unspecified vectors.
Apache PDFBox 2.0.14 does not properly initialize the XML parser, which allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted XFDF.
Apache James ManagedSieve implementation alongside with the file storage for sieve scripts is vulnerable to path traversal, allowing reading and writing any file. This vulnerability had been patched in Apache James 3.6.1 and higher. We recommend the upgrade. Distributed and Cassandra based products are also not impacted.
In Apache James, using Jazzer fuzzer, we identified that an IMAP user can craft IMAP LIST commands to orchestrate a Denial Of Service using a vulnerable Regular expression. This affected Apache James prior to 3.6.1 We recommend upgrading to Apache James 3.6.1 or higher , which enforce the use of RE2J regular expression engine to execute regex in linear time without back-tracking.
In Apache James, while fuzzing with Jazzer the IMAP parsing stack, we discover that crafted APPEND and STATUS IMAP command could be used to trigger infinite loops resulting in expensive CPU computations and OutOfMemory exceptions. This can be used for a Denial Of Service attack. The IMAP user needs to be authenticated to exploit this vulnerability. This affected Apache James prior to version 3.6.1. This vulnerability had been patched in Apache James 3.6.1 and higher. We recommend the upgrade.
Apache James prior to release 3.6.1 is vulnerable to a buffering attack relying on the use of the STARTTLS command. This can result in Man-in -the-middle command injection attacks, leading potentially to leakage of sensible information.
Apache James prior to release 3.6.3 and 3.7.1 is vulnerable to a buffering attack relying on the use of the STARTTLS command. Fix of CVE-2021-38542, which solved similar problem fron Apache James 3.6.1, is subject to a parser differential and do not take into account concurrent requests.
Fix of CVE-2021-40525 do not prepend delimiters upon valid directory validations. Affected implementations include: - maildir mailbox store - Sieve file repository This enables a user to access other users data stores (limited to user names being prefixed by the value of the username being used).
Severity: low
Affected versions:
- Apache James Mime4J through 0.8.9
Description:
Improper input validation allows for header injection in MIME4J library when using MIME4J DOM for composing message. This can be exploited by an attacker to add unintended headers to MIME messages.

Severity: important
Affected versions:
- Apache James server through 3.7.4 - Apache James server 3.8 through 3.8.0
Description:
Apache James prior to versions 3.8.1 and 3.7.5 is vulnerable to SMTP smuggling.
A lenient behaviour in line delimiter handling might create a difference of interpretation between the sender and the receiver which can be exploited by an attacker to forge an SMTP envelop, allowing for instance to bypass SPF checks.
The patch implies enforcement of CRLF as a line delimiter as part of the DATA transaction.
We recommend James users to upgrade to non vulnerable versions.
