Medium [CVE-2026-47086] Information disclosure via URLAUTH token bypass of Access Control Lists
A flaw was found in cyrus-imapd. An authenticated user could exploit this vulnerability by minting a URLAUTH token through the GENURLAUTH command. This allows bypassing Access Control Lists (ACLs), which are rules that control access to mailboxes. Consequently, an attacker could read mail from any mailbox, even without having been granted explicit read permissions. Red Hat severity: Moderate — CVSS 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N). Weakness: CWE-639. 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. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE.
Medium [CVE-2026-56434] Heap buffer over-read allows memory modification or denial of service
A vulnerability in NGINX's ngx_http_ssi_module allows an unauthenticated MITM attacker to trigger a heap buffer over-read by manipulating upstream server responses. This requires SSI, proxy_pass, and proxy_buffering off to be configured, and can result in memory modification or a Denial of Service (DoS). This Moderate severity vulnerability in NGINX affects configurations utilizing the `ngx_http_ssi_module` alongside `proxy_pass` and `proxy_buffering off`. Exploitation requires an unauthenticated man-in-the-middle attacker to control upstream server responses, leading to limited memory modification or a worker process restart. The specific combination of directives and an active MITM position limits the overall impact. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H). Weakness: CWE-125. Affected Red Hat products: Red Hat Hardened Images; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat Lightspeed proxy 1. Red Hat lists Red Hat Hardened Images as not affected. Red Hat fixing advisory: RHSA-2026:46012.
Medium [CVE-2026-50659] .NET:.NET: Network Spoofing Vulnerability

Red Hat lists fixing advisory RHSA-2026:41895 with package dotnet8-0-main-8.0.129-2.1.hum1, dotnet9.0-0:9.0.119-1.el9_8, dotnet9.0-0:9.0.119-1.el8_10, dotnet9-0-main-9.0.119-1.hum1. Affected products named by the advisory: Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 1.
Medium [CVE-2026-59888] com.fasterxml.jackson.core/jackson-databind: tools.jackson.core/jackson-databind: jackson-databind: @JsonIgnore bypass in Java Records
jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.15.0 until 2.18.8, 2.21.4, and 3.1.4, Java Records using a PropertyNamingStrategy can bypass @JsonIgnore because POJOPropertiesCollector._removeUnwantedIgnorals() records an ignored component under its original implicit name before _renameUsing() applies the naming strategy, allowing the renamed JSON key to be assigned to the Record constructor parameter. This issue is fixed in versions 2.18.8, 2.21.4, and 3.1.4. Consequently, an untrusted client could set internal or privileged components from external input, potentially leading to unauthorized modification or disclosure of sensitive data. Moderate impact. This flaw in jackson-databind allows an attacker to bypass the @JsonIgnore annotation when deserializing Java Records that utilize a PropertyNamingStrategy. Red Hat products using affected versions of jackson-databind for deserialization of external input into Java Records with PropertyNamingStrategy are susceptible. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N). Weakness: CWE-915. Affected products named by the advisory: OpenShift Serverless; Red Hat AI Inference Server; Red Hat AMQ Broker 7; Red Hat Ansible Automation Platform 2; and 13 more.
Medium [CVE-2026-0716 +1] Libsoup: incomplete fix for CVE-2026-0716: out-of-bounds read in libsoup websocket frame processing (unmasked path)
The fix for CVE-2026-0716 (commit 6ff7ef0, libsoup 3.6.6) placed the integer overflow guard inside the if (masked) block, leaving unmasked server-to-client frames unprotected. A malicious WebSocket server can send a crafted unmasked frame with a payload length near UINT64_MAX to trigger an OOB read in a libsoup-based client when max_incoming_payload_size is set to 0. This vulnerability is rated Moderate for Red Hat because it requires a non-default configuration where max_incoming_payload_size is explicitly set to 0 or unset in libsoup's WebSocket frame processing. In typical Red Hat deployments, this configuration is not enabled by default, limiting the exposure to memory disclosure or application instability. Red Hat severity: Moderate — CVSS 4.8 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 10. Red Hat does not currently list a fixing RHSA for this CVE.
Medium [CVE-2026-49844] Malformed JSON output due to improper encoding of floating-point values
Improper encoding of non-finite floating-point values during MapMessage JSON serialization in Apache Log4j API produces output that is not valid JSON. The fix for CVE-2026-34481 did not cover all code paths: when a MapMessage contains a non-finite IEEE 754 value (NaN, Infinity, or -Infinity), MapMessage.asJson() emits the corresponding bare token. RFC 8259 does not permit these tokens, so a conformant parser rejects the resulting document. The defect is reachable only when both of the following conditions hold: * The application uses the message resolver of JsonTemplateLayout or any other layout that relies on MapMessage.asJson() or MapMessage.getFormattedMessage(new String[]{"JSON"}). * The application logs a MapMessage that contains an attacker-controlled floating-point value. An attacker who can supply a non-finite value can cause the affected layout to emit malformed JSON, which may corrupt the enclosing log record or disrupt downstream log ingestion and parsing. Users are advised to upgrade to Apache Log4j API 2.25.5 or 2.26.1, both of which emit RFC 8259-compliant JSON for non-finite values. This can corrupt log records or disrupt downstream log ingestion and parsing, potentially leading to a Denial of Service (DoS) or information integrity issues.
