Vulnerability	Summary	Fixed by
VCID-46bv-6b7y-3bca Aliases: CVE-2020-11996 GHSA-53hp-jpwq-2jgq	A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0-M1 to 10.0.0-M5, 9.0.0.M1 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive.	10.0.0-M6 Affected by 2 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }}
VCID-66kh-s6cr-tqf9 Aliases: CVE-2020-9484 GHSA-344f-f5vg-2jfj	When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed.	10.0.0-M5 Affected by 2 other vulnerabilities. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} {{ fixed_by_vuln.vulnerability_id }} 10.0.2 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-885s-t4dx-dybv Aliases: CVE-2021-33037 GHSA-4vww-mc66-62m6	Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.	10.0.7 Affected by 0 other vulnerabilities.
VCID-a8gk-n8bq-87cp Aliases: CVE-2021-24122 GHSA-2rvv-w9r2-rg7m	When serving resources from a network location using the NTFS file system, Apache Tomcat versions 10.0.0-M1 to 10.0.0-M9, 9.0.0.M1 to 9.0.39, 8.5.0 to 8.5.59 and 7.0.0 to 7.0.106 were susceptible to JSP source code disclosure in some configurations. The root cause was the unexpected behaviour of the JRE API File.getCanonicalPath() which in turn was caused by the inconsistent behaviour of the Windows API (FindFirstFileW) in some circumstances.	10.0.0-M10 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-dy6m-zt6r-9ubd Aliases: CVE-2021-41079 GHSA-59g9-7gfx-c72p	Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2 did not properly validate incoming TLS packets. When Tomcat was configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet could be used to trigger an infinite loop resulting in a denial of service.	10.0.4 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-dzan-r49k-kqab Aliases: CVE-2020-13934 GHSA-vf77-8h7g-gghp	An h2c direct connection to Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M5 to 9.0.36 and 8.5.1 to 8.5.56 did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service.	10.0.0-M7 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-j8tk-s915-pbfy Aliases: CVE-2021-43980 GHSA-jx7c-7mj5-9438	The simplified implementation of blocking reads and writes introduced in Tomcat 10 and back-ported to Tomcat 9.0.47 onwards exposed a long standing (but extremely hard to trigger) concurrency bug in Apache Tomcat 10.1.0 to 10.1.0-M12, 10.0.0-M1 to 10.0.18, 9.0.0-M1 to 9.0.60 and 8.5.0 to 8.5.77 that could cause client connections to share an Http11Processor instance resulting in responses, or part responses, to be received by the wrong client.	10.0.20 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }} 10.1.0-M14 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-kwab-3s4q-eka4 Aliases: CVE-2021-30640 GHSA-36qh-35cm-5w2w	A vulnerability in the JNDI Realm of Apache Tomcat allows an attacker to authenticate using variations of a valid user name and/or to bypass some of the protection provided by the LockOut Realm. This issue affects Apache Tomcat 10.0.0-M1 to 10.0.5; 9.0.0.M1 to 9.0.45; 8.5.0 to 8.5.65.	10.0.6 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-n3ab-nk7c-hqc9 Aliases: CVE-2021-25329 GHSA-jgwr-3qm3-26f3	The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue.	10.0.2 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-nmq2-8ysj-4fbc Aliases: CVE-2022-42252 GHSA-p22x-g9px-3945	If Apache Tomcat 8.5.0 to 8.5.82, 9.0.0-M1 to 9.0.67, 10.0.0-M1 to 10.0.26 or 10.1.0-M1 to 10.1.0 was configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (the default for 8.5.x only), Tomcat did not reject a request containing an invalid Content-Length header making a request smuggling attack possible if Tomcat was located behind a reverse proxy that also failed to reject the request with the invalid header.	10.0.27 Affected by 0 other vulnerabilities. 10.1.1 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-nvbx-q971-skgm Aliases: CVE-2020-13935 GHSA-m7jv-hq7h-mq7c	The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service.	10.0.0-M7 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-p8q2-pt96-5ye8 Aliases: CVE-2022-34305 GHSA-6j88-6whg-x687	In Apache Tomcat 10.1.0-M1 to 10.1.0-M16, 10.0.0-M1 to 10.0.22, 9.0.30 to 9.0.64 and 8.5.50 to 8.5.81 the Form authentication example in the examples web application displayed user provided data without filtering, exposing a XSS vulnerability.	10.0.23 Affected by 0 other vulnerabilities. 10.1.0-M17 Affected by 0 other vulnerabilities.
VCID-qkx6-32cj-jfbp Aliases: CVE-2022-29885 GHSA-r84p-88g2-2vx2	The documentation of Apache Tomcat 10.1.0-M1 to 10.1.0-M14, 10.0.0-M1 to 10.0.20, 9.0.13 to 9.0.62 and 8.5.38 to 8.5.78 for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and integrity protection, it does not protect against all risks associated with running over any untrusted network, particularly DoS risks.	10.0.21 Affected by 0 other vulnerabilities. 10.1.0-M15 Affected by 0 other vulnerabilities.
VCID-ran8-rnqn-tkbc Aliases: CVE-2020-17527 GHSA-vvw4-rfwf-p6hx	While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests.	10.0.0-M10 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-t2ne-75ck-eqcr Aliases: CVE-2021-25122 GHSA-j39c-c8hj-x4j3	When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one request to another meaning user A and user B could both see the results of user A's request.	10.0.2 Affected by 1 other vulnerability. This version is affected by these other vulnerabilities: {{ fixed_by_vuln.vulnerability_id }}
VCID-wgsc-dnn1-ukeq Aliases: CVE-2020-13943 GHSA-f268-65qc-98vg	If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources.	10.0.0-M8 Affected by 0 other vulnerabilities.
VCID-yrzk-1dbk-muhy Aliases: CVE-2026-29146 GHSA-h468-7pvh-8vr8		10.1.53 Affected by 5 other vulnerabilities.
