CVE-2026-47684 Sync-in Server: SSRF protection bypass via IPv4-mapped IPv6 addresses in regExpPrivateIP

Sync-in Server is a secure, open-source platform for file storage, sharing, collaboration, and syncing. Prior to version 2.3.0, the private IP blocklist regex used in the URL download feature does not match IPv4-mapped IPv6 addresses e.g. ::ffff:127.0.0.1, allowing SSRF protection to be bypassed ...

CVE-2026-47684 — Sync-in Server SSRF bypass (IPv4-mapped IPv6 addresses) Affected product: Sync-in Server (file storage/sharing/collaboration). Vulnerability: The private IP blocklist regex (regExpPrivateIP) used in the URL download feature does not match IPv4-mapped IPv6 addresses (e.g., ::ffff:...

CVE-2026-10640 Use-after-free reading `net_pkt` `iface` after send in IPv6 Neighbor Discovery (`ipv6_nbr.c`)

Zephyr's IPv6 Neighbor Discovery send paths netipv6sendna, netipv6sendns, netipv6sendrs in subsys/net/ip/ipv6nbr.c updated the per-interface ICMP-sent statistics by calling netpktifacepkt after netsenddatapkt had already returned successfully. On the success path the network stack owns and releas...

CVE-2026-10640

Zephyr's IPv6 Neighbor Discovery send paths netipv6sendna, netipv6sendns, netipv6sendrs in subsys/net/ip/ipv6nbr.c updated the per-interface ICMP-sent statistics by calling netpktifacepkt after netsenddatapkt had already returned successfully. On the success path the network stack owns and releas...

CVE-2026-10640

Summary: Zephyr’s IPv6 Neighbor Discovery send paths (ipv6_nbr.c) perform a use-after-free by reading iface from a freed net_pkt slab block when updating per-interface ICMP statistics, after the packet has been sent. This can corrupt iface-stats.icmp.sent or cause a crash/DoS if the slab memory i...

CVE-2026-10640 Use-after-free reading `net_pkt` `iface` after send in IPv6 Neighbor Discovery (`ipv6_nbr.c`)

CVE-2026-10638 Use-after-free in Zephyr ICMPv6 RX path when updating statistics after sending an echo reply or error

subsys/net/ip/icmpv6.c reads the network interface from a netpkt after that packet has been handed to nettrysenddata. In icmpv6handleechorequest and neticmpv6senderror, the post-send statistics update calls netpktifacereply/netpktifacepkt on the just-sent packet. The send path nettrysenddata -...

CVE-2026-10638

The CVE describes a use-after-free in Zephyr’s ICMPv6 RX path: after sending an ICMPv6 Echo Request or an error, post-send statistics update references net_pkt_iface(reply/pkt) on a packet that may already be freed by net_try_send_data (or by the driver/L2). If CONFIG_NET_TC_TX_COUNT is 0 or the ...

PT-2026-50129

Summary When an application using Pydantic AI opts a URL into force download='allow-local' which disables the default block on private/internal IPs and runs on a network that routes the affected IPv6 transition forms NAT64- or ISATAP-configured networks, the cloud-metadata blocklist could be...

RHEL 9 : podman (RHSA-2026:26445)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:26445 advisory.

Crawl4AI: SSRF filter bypass in Docker server via IPv6 transition forms (NAT64 / 6to4 / unspecified / v4-mapped)

The Docker API server's SSRF protection validatewebhookurl / validateurldestination in deploy/docker/utils.py used an explicit IPv4/IPv6 CIDR blocklist that missed several address families. An attacker could reach internal services and cloud metadata endpoints e.g. 169.254.169.254 despite the...
