Summary
ACL configured in ip_allow.config or remap.config does not use IP addresses that are provided by PROXY protocol.
Users can use a new setting (proxy.config.acl.subjects) to choose which IP addresses to use for the ACL if Apache Traffic Server is configured to accept PROXY protocol.
This issue affects undefined: from 10.0.0 through 10.0.6, from 9.0.0 through 9.2.10.
Users are recommended to upgrade to version 9.2.11 or 10.0.6, which fixes the issue.

Summary
Apache Traffic Server accepts characters that are not allowed for HTTP field names and forwards malformed requests to origin servers. This can be utilized for request smuggling and may also lead cache poisoning if the origin servers are vulnerable.
This issue affects Apache Traffic Server: from 8.0.0 through 8.1.10, from 9.0.0 through 9.2.4.
Users are recommended to upgrade to version 8.1.11 or 9.2.5, which fixes the issue.
Severity ?
No CVSS data available.

CVE-2024-35161 (GCVE-0-2024-35161)
Vulnerability from cvelistv5 – Published: 2024-07-26 09:10 – Updated: 2025-11-03 21:54
VLAI?
Summary
Apache Traffic Server forwards malformed HTTP chunked trailer section to origin servers. This can be utilized for request smuggling and may also lead cache poisoning if the origin servers are vulnerable.
This issue affects Apache Traffic Server: from 8.0.0 through 8.1.10, from 9.0.0 through 9.2.4.
Users can set a new setting (proxy.config.http.drop_chunked_trailers) not to forward chunked trailer section.
Users are recommended to upgrade to version 8.1.11 or 9.2.5, which fixes the issue.
Severity ?
No CVSS data available.

CVE-2024-31309 (GCVE-0-2024-31309)
Vulnerability from cvelistv5 – Published: 2024-04-10 12:07 – Updated: 2025-11-04 18:30
VLAI?
Summary
HTTP/2 CONTINUATION DoS attack can cause Apache Traffic Server to consume more resources on the server. Version from 8.0.0 through 8.1.9, from 9.0.0 through 9.2.3 are affected.
Users can set a new setting (proxy.config.http2.max_continuation_frames_per_minute) to limit the number of CONTINUATION frames per minute. ATS does have a fixed amount of memory a request can use and ATS adheres to these limits in previous releases.
Users are recommended to upgrade to versions 8.1.10 or 9.2.4 which fixes the issue.
Severity ?
No CVSS data available.

CVE-2025-31698 (GCVE-0-2025-31698)
Vulnerability from nvd – Published: 2025-06-19 10:07 – Updated: 2025-06-20 13:32
VLAI?
Summary
ACL configured in ip_allow.config or remap.config does not use IP addresses that are provided by PROXY protocol.
Users can use a new setting (proxy.config.acl.subjects) to choose which IP addresses to use for the ACL if Apache Traffic Server is configured to accept PROXY protocol.
This issue affects undefined: from 10.0.0 through 10.0.6, from 9.0.0 through 9.2.10.
Users are recommended to upgrade to version 9.2.11 or 10.0.6, which fixes the issue.

Summary
Apache Traffic Server accepts characters that are not allowed for HTTP field names and forwards malformed requests to origin servers. This can be utilized for request smuggling and may also lead cache poisoning if the origin servers are vulnerable.
This issue affects Apache Traffic Server: from 8.0.0 through 8.1.10, from 9.0.0 through 9.2.4.
Users are recommended to upgrade to version 8.1.11 or 9.2.5, which fixes the issue.
Severity ?
No CVSS data available.

CVE-2024-35161 (GCVE-0-2024-35161)
Vulnerability from nvd – Published: 2024-07-26 09:10 – Updated: 2025-11-03 21:54
VLAI?
Summary
Apache Traffic Server forwards malformed HTTP chunked trailer section to origin servers. This can be utilized for request smuggling and may also lead cache poisoning if the origin servers are vulnerable.
This issue affects Apache Traffic Server: from 8.0.0 through 8.1.10, from 9.0.0 through 9.2.4.
Users can set a new setting (proxy.config.http.drop_chunked_trailers) not to forward chunked trailer section.
Users are recommended to upgrade to version 8.1.11 or 9.2.5, which fixes the issue.
Severity ?
No CVSS data available.

CVE-2024-31309 (GCVE-0-2024-31309)
Vulnerability from nvd – Published: 2024-04-10 12:07 – Updated: 2025-11-04 18:30
VLAI?
Summary
HTTP/2 CONTINUATION DoS attack can cause Apache Traffic Server to consume more resources on the server. Version from 8.0.0 through 8.1.9, from 9.0.0 through 9.2.3 are affected.
Users can set a new setting (proxy.config.http2.max_continuation_frames_per_minute) to limit the number of CONTINUATION frames per minute. ATS does have a fixed amount of memory a request can use and ATS adheres to these limits in previous releases.
Users are recommended to upgrade to versions 8.1.10 or 9.2.4 which fixes the issue.
Severity ?
No CVSS data available.
