Eclipse Wakaama before snapshot/2026-05-26 contains an unbounded memory allocation vulnerability in the CoAP Block1 handler within coap/block.c that allows unauthenticated remote attackers to exhaust server memory by sending a sequence of Block1 PUT requests with incrementing block numbers. Attackers can target the registration endpoint over UDP without authentication, causing the server to repeatedly reallocate a growing accumulation buffer by appending each block payload without enforcing any maximum total size limit, resulting in denial of service through memory exhaustion.

Open VSX Registry does not sanitize SVG files uploaded as extension icons prior to storage, and serves them with Content-Type: image/svg+xml without security headers such as Content-Security-Policy or Content-Disposition: attachment. This allows an attacker to publish an extension with a malicious SVG icon and achieve stored cross-site scripting (XSS) when a user navigates directly to the icon URL.

On deployments using local storage, script execution occurs within the Open VSX application origin, enabling session hijacking, authentication token theft, and unauthorized extension publishing. On deployments backed by external storage (such as open-vsx.org with an S3-backed CDN), execution is confined to the storage origin, reducing impact but still permitting phishing attacks and credential harvesting through attacker-crafted pages.

In Eclipse Theia versions prior to 1.71.0, the AI chat agent processed workspace file and directory names as part of its prompt context without distinguishing them from system instructions. An attacker could craft a malicious repository with adversarial directory or file names that, when analyzed by the AI agent, would cause the agent to follow attacker-controlled instructions (indirect prompt injection). Combined with other AI chat features available in untrusted workspaces, this enabled attack chains leading to data exfiltration via Markdown image rendering or arbitrary command execution via task definitions.

In Eclipse Theia versions prior to 1.71.0, files matching the pattern .prompts/.prompttemplate in a workspace were automatically loaded and could override or extend the AI agent's system prompts. An attacker could craft a malicious repository containing prompt template files that, when the workspace was opened in Theia, replaced the AI's system instructions with attacker-controlled content (indirect prompt injection). Combined with other AI chat features available in untrusted workspaces, this enabled attack chains leading to data exfiltration via Markdown image rendering or arbitrary command execution via task definitions.

In FileX before 6.4.2, the file support module for Eclipse Foundation ThreadX, there was a possible buffer overflow in the FileX RAM disk driver. It could cause a remote execurtion after receiving a crafted sequence of packets

In Eclipse Foundation NextX Duo before 6.4.4, a module of ThreadX, the nxsecuretlsprocessclienthello() function was missing length verification of certain SSL/TLS client hello message: the ciphersuite length and compression method length. In case of an attacker-crafted message with values outside of the expected range, it could cause an out-of-bound read.

In NetX Duo version before 6.4.4, the component of Eclipse Foundation ThreadX, there was an incorrect bound check resulting it out by two out of bound read.

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in nxicmpv6validateoptions() when handling a packet with ICMP6 options.

In NextX Duo's snmp addon versions before 6.4.4, a part of the Eclipse Foundation ThreadX, an attacker could cause an out-of-bound read by a crafted SNMPv3 security parameters.

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in nxipv4packetreceive() when handling unicast DHCP messages that could cause corruption of 4 bytes of memory.

In Eclipse Foundation NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in nxipv4optionprocess() when processing an IPv4 packet with the timestamp option.

In NetXDuo version before 6.4.4, a networking support module for Eclipse Foundation ThreadX, in the DHCPV6 client there was an unchecked index extracting the server DUID from the server reply. With a crafted packet, an attacker could cause an out of memory read.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in uxhostclassaudio10samparsefunc() when parsing a list of sampling frequencies.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in uxhostclassaudiodevicetypeget() when parsing a descriptor of an USB audio device.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in uxhostclassaudioalternatesettinglocate() when parsing a descriptor with attacker-controlled frequency fields.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in uxhostclassaudiostreamingsamplingget() when parsing a descriptor of an USB streaming device.

In USBX before 6.4.3, the USB support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in uxhostclasshidreportdescriptorget()  when parsing a descriptor of an USB HID device.

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in nxippacketreceive() function when received an Ethernet with type set as IP but no IP data.

In NetX Duo before 6.4.4, the networking support module for Eclipse Foundation ThreadX, there was a potential out of bound read issue in nxipv4packetreceive() function when received an Ethernet frame with less than 4 bytes of IP packet.

In NetX Duo version before 6.4.4, the component of Eclipse Foundation ThreadX, there was an incorrect bound check innxsecuretlsprocclienthellosupportedversionsextension() in the extension version field.

In NetX Duo version before 6.4.4, the component of Eclipse Foundation ThreadX, there was a potential out of bound read in nxsecuretlsprocessclienthello() because of a missing validation of PSK length provided in the user message.
