Descrição técnica

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.0 to 2.11.0, GetStyle's fill, border, and font extraction predicates check only upper bounds for attacker-controlled style-table indices. File.GetStyle relies on extractStyleCondFuncs predicates that allow negative FillID, BorderID, and FontID values to reach slice indexing. When a crafted styles.xml supplies a negative fillId, borderId, or fontId and the application reads the style, a negative identifier passes the upper-bound-only predicate and becomes a negative slice index, allowing an attacker to panic while reading cell styling. No fixed version is available as of this review.

———MONAI (Medical Open Network for AI) is an AI toolkit for health care imaging. Prior to 1.6.1, PydicomReader._get_affine() trusts non-finite values in the DICOM PixelSpacing, ImagePositionPatient, and ImageOrientationPatient fields and composes them into an affine matrix without validation. An unauthenticated attacker who can upload a crafted DICOM to a default MONAILabel deployment can propagate NaN or infinity values through LoadImaged, Spacingd, model inference, and output writing, causing inference failures, persistent datastore poisoning, or geometrically corrupted results. This issue is fixed in version 1.6.1.6h CVE-2026-463509.1 CRÍ

———dcmjs is a JavaScript implementation of DICOM manipulation. Prior to 0.52.0, the DecimalString and IntegerString implementations in src/ValueRepresentation.js sanitize text with a permissive regular expression and pass the result to JavaScript's Number constructor without validating finiteness or the DICOM value-representation rules. Scientific notation overflow in a DS or IS field can produce positive or negative Infinity, while stripping alphabetic characters from signed infinity text can leave a sign-only string that converts to NaN. IntegerString also accepts exponent notation and values outside the DICOM signed 32-bit IS range. Applications that trust these parsed values can propagate invalid numbers into spatial geometry, display windowing, dose scaling, frame counts, rescaling, or volume reconstruction, causing incorrect calculations or disrupted processing. This issue is fixed in version 0.52.0.7h CVE-2026-1167838.2 ALT

——0FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. Prior to 1.11.2, udptl_rx_packet() used a peer-controlled FEC entry count directly to fill five-entry FEC arrays in a mod_spandsp T.38 session. A larger count wrote sender-controlled error-recovery data beyond those arrays and persisted the oversized count for a later reconstruction pass. Any peer able to deliver UDPTL to an established T.38 fax session can reach the parser, including deployments using fax applications or a T.38 gateway. The memory corruption can crash FreeSWITCH and end every active call, although remote code execution has not been demonstrated. This issue is fixed in version 1.11.2.6h CVE-2026-715488.8 ALT

——0SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, AOR_Report::build_report_query_where incorporates a report editor's parameter_value when value_type=Field without sufficient validation. An authenticated user who can save a report can use SQL injection to read the entire SuiteCRM database. Disclosed data can include users.user_hash, OAuth2 tokens, CRM records, report definitions, and configuration data; the connector does not permit stacked queries, so direct write-through-injection is not supported. This issue is fixed in versions 7.15.2 and 8.10.2.9h CVE-2026-1232007.5 ALT

——0VRPN through 07.36 contains an out-of-bounds stack write vulnerability in vrpn_Endpoint::handle_sender_message() and handle_type_message() that allows unauthenticated remote peers to write outside a stack buffer via an unchecked length index. Attackers can connect, complete the version-cookie exchange, and send a SENDER_DESCRIPTION or TYPE_DESCRIPTION message with an out-of-range or negative index to crash the process.9h CVE-2026-1164722.7 BAI

——0A security issue was discovered in ingress-nginx where a user with permission to create an Ingress may be able to cause denial of service of the ingress-nginx data plane, or possibly redirect traffic from other Ingresses. Kubernetes clusters are only affected if they are using ingress-nginx. Due to a missing check, the mirror-target Ingress annotation can be used to target an unauthenticated configuration API within the ingress-nginx controller, allowing write commands to be submitted. Corrupting the data within that configuration API results in all traffic through ingress-nginx being dropped until an Ingress configuration change or a controller restart causes the data to be recreated correctly. In principle, this write access could also be used to redirect traffic from other Ingresses controlled by the same ingress-nginx instance. In practice, there is negligible additional risk: such redirection would require privileged information about internal ingress-nginx state, and users can already redirect traffic from other Ingresses controlled by the same ingress-nginx anyway.6h
