Latest Red Hat advisories
Medium [CVE-2026-1539] Libsoup: libsoup: credential leakage via http redirects
A flaw was found in the libsoup HTTP library that can cause proxy authentication credentials to be sent to unintended destinations. When handling HTTP redirects, libsoup removes the Authorization header but does not remove the Proxy-Authorization header if the request is redirected to a different host. As a result, sensitive proxy credentials may be leaked to third-party servers. Applications using libsoup for HTTP communication may unintentionally expose proxy authentication data. The Red Hat Product Security team has assessed the severity of this vulnerability as Medium. Exploitation requires network access but does not require authentication, user interaction, or special privileges. Successful exploitation may result in the disclosure of proxy authentication credentials to unintended third parties. While the issue does not directly allow code execution or service disruption, leakage of authentication material represents a meaningful confidentiality risk. The root cause is improper handling of sensitive headers during HTTP redirect processing. Red Hat severity: Moderate — CVSS 5.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N). Weakness: CWE-201. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE.
Medium [CVE-2026-1536] Libsoup: libsoup: http header injection or response splitting via crlf injection in content-disposition header
A flaw was found in libsoup. An attacker who can control the input for the Content-Disposition header can inject CRLF (Carriage Return Line Feed) sequences into the header value. These sequences are then interpreted verbatim when the HTTP request or response is constructed, allowing arbitrary HTTP headers to be injected. This vulnerability can lead to HTTP header injection or HTTP response splitting without requiring authentication or user interaction. This is a MODERATE impact flaw in the libsoup HTTP library, allowing CRLF injection via the `soup_message_headers_set_content_disposition()` function. Red Hat products are affected if they use libsoup in a configuration that passes unsanitized, untrusted input to this function. Red Hat severity: Moderate — CVSS 5.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N). Weakness: CWE-93. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: libsoup3.

Medium [CVE-2026-1489] Glib: glib: memory corruption via integer overflow in unicode case conversion
A flaw was found in GLib. An integer overflow vulnerability in its Unicode case conversion implementation can lead to memory corruption. By processing specially crafted and extremely large Unicode strings, an attacker could trigger an undersized memory allocation, resulting in out-of-bounds writes. This could cause applications utilizing GLib for string conversion to crash or become unstable. This vulnerability is rated Moderate for Red Hat products. Applications that handle untrusted, large Unicode input and utilize GLib for string conversion may be susceptible, potentially resulting in crashes or instability. Red Hat severity: Moderate — CVSS 5.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L). Weakness: CWE-787. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: bootc; Red Hat package: glib2; Red Hat package: glycin-loaders; Red Hat package: loupe; and 4 more. Affected products named by the advisory: Red Hat package: mingw-glib2; Red Hat package: papers; Red Hat package: rpm-ostree; Red Hat package: librsvg2.
Medium [CVE-2026-1484] Glib: integer overflow leading to buffer underflow and out-of-bounds write in glib g_base64_encode
A flaw was found in the GLib Base64 encoding routine when processing very large input data. Due to incorrect use of integer types during length calculation, the library may miscalculate buffer boundaries. This can cause memory writes outside the allocated buffer. Applications that process untrusted or extremely large Base64 input using GLib may crash or behave unpredictably. This vulnerability is rated Moderate for Red Hat products. The flaw in GLib's Base64 encoding implementation requires an application to pass excessively large or untrusted input to the g_base64_encode() API. Exploitation could lead to application crashes or memory corruption. Red Hat severity: Moderate — CVSS 4.2 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L). Weakness: CWE-787. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: bootc; Red Hat package: glib2; Red Hat package: glycin-loaders; Red Hat package: loupe; and 4 more. Affected products named by the advisory: Red Hat package: mingw-glib2; Red Hat package: papers; Red Hat package: rpm-ostree; Red Hat package: librsvg2.
Medium [CVE-2026-1467] Libsoup: libsoup: http header injection via specially crafted urls when an http proxy is configured
A flaw was found in libsoup, an HTTP client library. This vulnerability, known as CRLF (Carriage Return Line Feed) Injection, occurs when an HTTP proxy is configured and the library improperly handles URL-decoded input used to create the Host header. A remote attacker can exploit this by providing a specially crafted URL containing CRLF sequences, allowing them to inject additional HTTP headers or complete HTTP request bodies. This can lead to unintended or unauthorized HTTP requests being forwarded by the proxy, potentially impacting downstream services. This vulnerability is rated Moderate for Red Hat products. Red Hat severity: Moderate — CVSS 5.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N). Weakness: CWE-93. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: libsoup3.
