Openstack Swift vulnerabilities

CVE-2017-16613 [CRITICAL] CWE-287 CVE-2017-16613: An issue was discovered in middleware.py in OpenStack Swauth through 1.2.0 when used with OpenStack An issue was discovered in middleware.py in OpenStack Swauth through 1.2.0 when used with OpenStack Swift through 2.15.1. The Swift object store and proxy server are saving (unhashed) tokens retrieved from the Swauth middleware authentication mechanism to a log file as part of a GET URI. This allows attackers to bypass authentication by inserting a

CVE-2012-4406 [CRITICAL] CWE-502 CVE-2012-4406: OpenStack Object Storage (swift) before 1.7.0 uses the loads function in the pickle Python module un OpenStack Object Storage (swift) before 1.7.0 uses the loads function in the pickle Python module unsafely when storing and loading metadata in memcached, which allows remote attackers to execute arbitrary code via a crafted pickle object.

CVE-2026-71190 [HIGH] CWE-1333 CVE-2026-71190: In OpenStack Swift through 2.38.0, the proxy server Accept header parser contains a regular expressi In OpenStack Swift through 2.38.0, the proxy server Accept header parser contains a regular expression vulnerable to catastrophic backtracking (ReDoS). The "qdtext" pattern (?:[^"]|\\.)* allows an unauthenticated remote attacker to send a crafted Accept header that causes exponential CPU consumption in the proxy worker. A payload of 32 backslash-char

CVE-2026-71191 [MEDIUM] CWE-863 CVE-2026-71191: In OpenStack Swift through 2.38.0, S3API middleware does not enforce that semantic x-amz-* headers a In OpenStack Swift through 2.38.0, S3API middleware does not enforce that semantic x-amz-* headers are covered by the SigV4 signature on presigned URL requests. An attacker who obtains a presigned PUT URL can inject an unsigned X-Amz-Copy-Source header, causing Swift to perform a server-side copy from an arbitrary source object using the signer's au

CVE-2022-47950 [MEDIUM] CWE-552 CVE-2022-47950: An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0. By suppl An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0. By supplying crafted XML files, an authenticated user may coerce the S3 API into returning arbitrary file contents from the host server, resulting in unauthorized read access to potentially sensitive data. This impacts both s3api deployments (Rocky or later),

CVE-2016-0737 [HIGH] CWE-399 CVE-2016-0737: OpenStack Object Storage (Swift) before 2.4.0 does not properly close client connections, which allo OpenStack Object Storage (Swift) before 2.4.0 does not properly close client connections, which allows remote attackers to cause a denial of service (proxy-server resource consumption) via a series of interrupted requests to a Large Object URL.

CVE-2026-71192 [MEDIUM] CWE-863 CVE-2026-71192: In OpenStack Swift through 2.38.0, the S3API middleware does not sanitize Swift-native control heade In OpenStack Swift through 2.38.0, the S3API middleware does not sanitize Swift-native control headers (X-Copy-From, X-Copy-From-Account) from S3 API requests when s3_acl=true. An attacker can inject these headers into a signed PUT request targeting their own bucket, causing Swift to perform a server-side copy from another tenant's private object. T

CVE-2016-0738 [HIGH] CWE-399 CVE-2016-0738: OpenStack Object Storage (Swift) before 2.3.1 (Kilo), 2.4.x, and 2.5.x before 2.5.1 (Liberty) do not OpenStack Object Storage (Swift) before 2.3.1 (Kilo), 2.4.x, and 2.5.x before 2.5.1 (Liberty) do not properly close server connections, which allows remote attackers to cause a denial of service (proxy-server resource consumption) via a series of interrupted requests to a Large Object URL.

CVE-2013-2161 [HIGH] CWE-94 OpenStack Swift Unchecked user input in XML responses OpenStack Swift Unchecked user input in XML responses XML injection vulnerability in account/utils.py in OpenStack Swift Folsom, Grizzly, and Havana allows attackers to trigger invalid or spoofed Swift responses via an account name.

CVE-2026-49017 [MEDIUM] CWE-835 CVE-2026-49017: In OpenStack Swift before 2.36.2 and 2.37.2, s3api middleware enters an infinite loop when processin In OpenStack Swift before 2.36.2 and 2.37.2, s3api middleware enters an infinite loop when processing a truncated aws-chunked PUT request body. The StreamingInput class repeatedly appends an empty buffer and re-reads, causing the proxy-server worker handling the request to become permanently unresponsive with increasing CPU and memory consumption. A

CVE-2026-50221 [MEDIUM] CWE-918 CVE-2026-50221: In OpenStack Swift before 2.37.2, proxy-server does not strip internal update headers (X-Container-H In OpenStack Swift before 2.37.2, proxy-server does not strip internal update headers (X-Container-Host, X-Container-Device, X-Delete-At-Host, X-Delete-At-Device) from client requests before forwarding them to object-servers. An authenticated user with write access can inject these headers to redirect container update requests to an attacker-control

CVE-2026-97149 [MEDIUM] CWE-184 CVE-2026-97149: In OpenStack Swift before 2.38.2, the tempurl middleware does not reject the X-Copy-From header on P In OpenStack Swift before 2.38.2, the tempurl middleware does not reject the X-Copy-From header on PUT requests. A TempURL signature only covers the method, expiry, and path, and thus the list of disallowed headers is the only defense against a signed PUT request changing what the request does. An attacker holding a PUT TempURL for a single object c

CVE-2015-1856 [MEDIUM] CWE-264 CVE-2015-1856: OpenStack Object Storage (Swift) before 2.3.0, when allow_version is configured, allows remote authe OpenStack Object Storage (Swift) before 2.3.0, when allow_version is configured, allows remote authenticated users to delete the latest version of an object by leveraging listing access to the x-versions-location container.

CVE-2013-6396 [MEDIUM] CWE-310 CVE-2013-6396: The OpenStack Python client library for Swift (python-swiftclient) 1.0 through 1.9.0 does not verify The OpenStack Python client library for Swift (python-swiftclient) 1.0 through 1.9.0 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

CVE-2014-7960 [MEDIUM] CWE-399 CVE-2014-7960: OpenStack Object Storage (Swift) before 2.2.0 allows remote authenticated users to bypass the max_me OpenStack Object Storage (Swift) before 2.2.0 allows remote authenticated users to bypass the max_meta_count and other metadata constraints via multiple crafted requests which exceed the limit when combined.

CVE-2017-8761 [MEDIUM] CWE-200 CVE-2017-8761: In OpenStack Swift through 2.10.1, 2.11.0 through 2.13.0, and 2.14.0, the proxy-server logs full tem In OpenStack Swift through 2.10.1, 2.11.0 through 2.13.0, and 2.14.0, the proxy-server logs full tempurl paths, potentially leaking reusable tempurl signatures to anyone with read access to these logs. All Swift deployments using the tempurl middleware are affected.

CVE-2015-5223 [MEDIUM] CWE-200 CVE-2015-5223: OpenStack Object Storage (Swift) before 2.4.0 allows attackers to obtain sensitive information via a OpenStack Object Storage (Swift) before 2.4.0 allows attackers to obtain sensitive information via a PUT tempurl and a DLO object manifest that references an object in another container.

CVE-2014-0006 [MEDIUM] CWE-200 CVE-2014-0006: The TempURL middleware in OpenStack Object Storage (Swift) 1.4.6 through 1.8.0, 1.9.0 through 1.10.0 The TempURL middleware in OpenStack Object Storage (Swift) 1.4.6 through 1.8.0, 1.9.0 through 1.10.0, and 1.11.0 allows remote attackers to obtain secret URLs by leveraging an object name and a timing side-channel attack.
